Multiple wavelength generation from a mode locked silicon evanescent laser

In this paper, an improved performance of mode locked lasers using silicon evanescent laser approach is shown. Its potential application as multiple wavelength WDM (wavelength division multiplexing) sources is presented. Results from a hybrid silicon evanescent mode locked laser (ML-SEL) that creates a comb of over 100 optical modes within 10-dB of the peak mode output power are also presented. The linewidth and OSNR of several longitudinal modes across the spectrum of this comb are examined as well as the results from CW laser seed light injection into the ML-SEL in stabilizing the modes.
