Research Summary
Digital signal processing is a powerful technique for storing, analyzing, and manipulatingdigital signals. Ultimately, the quality of the signal to be processed is determined bythe performance of the analog-to-digital converter (ADC) which is used to sample theoriginal analog signal in the first place and produce a digital representation of it.Photonics has been used to increase the performance of electronic ADCs since the 1970s,forming what is now generally termed the photonic ADC where a mode-locked laser istraditionally used as the sampling pulse source. However, such pulsed optical sources areexpensive, require constant stability adjustments, and do not allow flexible samplingfrequencies, and as a result their applications are limited. This proposed project willinvestigate a new high-speed and high-performance photonic sampling technique as a firststep in performing analog-to-digital conversion with the added advantage of havinghighly flexible sampling frequencies compared to other techniques based on the expensiveand bulky mode-locked lasers.
