Title
Noise Reduction And Control In Modelocked Semiconductor Diode Lasers For Use In Next-Generation All-Optical Analog-To-Digital Converters
Abstract
External-cavity, actively-modelocked semiconductor diode lasers (SDLs) have proven to be attractive candidates for forming the backbone of next-generation analog-to-digital converters (ADCs), which are currently being developed to sample signals at repetition rates exceeding several GHz with up to 12 bits of digital resolution. Modelocked SDLs are capable of producing waveform-sampling pulse trains with very low temporal jitter (phase noise) and very small fluctuations in pulse height (amplitude noise) - two basic conditions that must be met in order for high-speed ADCs to achieve projected design goals. Single-wavelength modelocked operation (at nominal repetition frequencies of 400 MHz) has produced pulse trains with very low amplitude noise (approx. 0.08%), and the implementation of a phase-locked-loop (PLL) has been effective in reducing the system's low-frequency phase noise (RMS timing jitter for offset frequencies between 10 Hz and 10 KHz has been reduced from 240 fs to 27 fs).
