Abstract: I am a Manufacturing Engineer for Lockheed Martin in the Optical Components Center. I work in a class 1000 clean room where we use a photolithography process to make the coating for the exterior windows under the F-35 that shield EOTS (Electro-Optic Targeting System). There are many daily challenges that I face as an engineer and not all pertain to engineering itself. It was not an easy adjustment coming from school and going straight into industry and I will share what some of the challenges are and how I work towards overcoming them. I will explain why I chose life in industry instead of academia and my personal battle between getting a Master’s vs. a PhD. I will also share the details about how I landed my interview and position for my dream job and my journey that lead me here.

Biography: Originally from Florida, I wanted to stay in the sunshine state. I graduated from UCF undergrad with a degree in Physics in May 2014. While I was in undergrad I started doing research with the Nonlinear Optics group, where I continued doing research while pursuing my Masters. I graduated with my Master’s in December 2015 and had a job lined up since September 2015. I am currently a Manufacturing Engineer at Lockheed Martin.

LPTH Press Release: LightPath Joins Nanomaterial Innovation Limited As Key Industrial Partner On National Science Foundation Phase II SBIR Program

For Immediate Release:

LightPath Joins Nanomaterial Innovation Limited
As Key Industrial Partner
On National Science Foundation
Phase II SBIR Program


    ORLANDO, FL - (June 29, 2016) - LightPath Technologies, Inc. (NASDAQ: LPTH) (“LightPath”, the “Company” or “we”), a leading vertically integrated global manufacturer,distributor and integrator of proprietary optical and infrared components and high-level assemblies, today announced it has won a $200,000 sub-award from the National Science Foundation for a Phase II Small Business Innovation Research titled “Carbide bonded graphene coating for enhanced glass molding.”  LightPath is part of the research team led by the primary grantee of Nanomaterial Innovation Limited (NIL), a spin-off from The Ohio State University.

    Graphene has emerged as one of the most intriguing materials for optical applications in recent years due to its natural properties possessing the highest strength and thermal conductivity known to man. Despite these outstanding properties, commercial applications are limited by the difficulty of scaling up graphene fabrication. However, a novel graphene-containing film deposition method developed at The Ohio State University/NIL could help to overcome this challenge and allow graphene to be utilized in a wide variety of applications including precision glass molding.

    During Phase I, NIL showed that when used for mold release this graphene coating provided potential advantages for molding both visible and infrared glasses. As a recognized worldwide leader in the handling, production and commercialization of precision optical technologies, LightPath was invited to participate in the research program.  Now in Phase II, LightPath joins NIL as an industrial partner and will use its experience in molding optics to apply this coating to a production environment.

    Anticipated benefits include enhanced mold lifetimes, improved molding yields, and, therefore, reduced costs for both visible and infrared optics. The work will focus on molding both singlet lenses as well as multi-cavity optics.  These optical components may be critical as an enabling factor for driving enhanced functionality and lower cost for end products used in military, public safety, medical, industrial, automotive markets.

About National Science Foundation (SBIR program):

Recent progress on high-energy ultrafast laser systems in RIKEN

Seminar Yuxi FU- in PSB 160/161 @ 1:30 pm Monday June 13

Recent progress on high-energy ultrafast laser systems in RIKEN

Yuxi FU
RIKEN Center for Advanced Photonics, Japan

In this seminar, two of our recent work will be presented. The first one is developing high-energy infrared fs laser using a dual-chirped optical parametric amplification (DC-OPA) scheme. In the DC-OPA scheme, a high-energy fs laser pulse is temporally stretched by introducing an amount of temporal chirp and is used as a pump for an OPA system. In this way, the pump energy can be scaled up without damaging nonlinear crystals. Simultaneously, the seed pulse of the OPA is also temporally broadened to achieve good conversion efficiency. Because both of the pump and seed pulses are temporally chirped, the method is dubbed as dual-chirped OPA. In this novel method, it is important not only to optimize the chirp value but also to use the same chirp sign. By using the DC-OPA method, we successfully demonstrated its excellent energy scaling ability and obtained more than 100 mJ output (signal + idler) energy. To the best of our knowledge, this is the first time for an ultrafast infrared laser to reach the 100 mJ class. Such a high-energy infrared fs laser is very useful for energy scaling of sub-keV high harmonics generation and intense isolated attosecond pulse generation by infrared two color gating (IR-TCG) method.

The other one is carrier-envelope phase (CEP) stabilization of a high-energy, low-repetition rate laser. A high-repetition rate reference pulse, which copropagates with the high-energy pulse though the power amplifier and compressor, is employed to characterize and stabilize its CEP. CEPs of the high-energy pulses are indirectly stabilized to below 600 mrad RMS level under an out-of-loop measurement (single-shot). What’s more, we experimentally investigated CEP stabilization affected by energy fluctuation, sampling/feedback frequency and thermal effect. The method can be employed to stabilize CEPs of 100-TW or even PW class lasers.

TOMORROW! SID & IEEE Joint Student Chapter Seminar: "Light Extraction of OLED Display by Microstructured Film Attachment" By Dr. Jiun-Haw Lee, 6.8.16/11:00AM-12:00PM/CREOL RM 103

SID & IEEE Joint Student Chapter Seminar: "Light Extraction of OLED Display by Microstructured Film Attachment" By Dr. Jiun-Haw Lee
Wednesday, June 8, 2016 11:00 AM to 12:00 PM
CREOL Room 103

Dr. Jiun-Haw LeeGraduate Institute of Photonics and Optoelectronics and Department of Electrical Engineering, National Taiwan University

Abstract:
In this talk, we used different micro-structured films to improve the light extraction (LE) from an organic light-emitting diode (OLED) for display application. Different micro-structures and OLED thin-film stacks were deigned and fabricated for optimizing the LE efficiency. For display applications, not only the LE efficiency, but also the image quality should be taken into consideration. After the optimization of pixel layout and the micro-structure, we can improve the LE efficiency of an OLED display with almost indistinguishable image blurring.
