Abstract:
Traditionally, optical power meters have been used for
continuous-wave (CW) light sources to measure average power. Recent
advancements in photonics technologies have broadened the applications horizon
into many different areas. An increasingly larger number of complex and diverse
forms of light sources are designed into various systems and experimental
setups. These complex light sources drive the need for more sensitive and
versatile power measurement capabilities with unprecedented accuracy.
It is particularly challenging to measure a
low-average-power pulsed light source, such as an LED or a low-power laser
diode, especially when the electrical designers do not know the detailed
optical characteristics of the light source. In addition to average optical power,
many other parameters about the light source are important to obtain. For
instance, what does the optical signal look like? Key information such as
shape, frequency, and power level is needed to determine the system power
budget and the overall system performance, as well as to validate the
effectiveness of lower cost components. It is also important to identify which
signal characteristics the detector or the detection system will measure.
Researchers and engineers are interested in the pulse width and pulse shape of
the signal.
