In this paper, a chip-scale Raman silicon laser and amplifier based on a ring resonator architecture are presented. Lasing threshold and efficiency are significantly improved from the previous experiments. Much lower pump power and smaller foot print are needed for the ring resonator amplifier compared to Raman amplifier in linear configuration due to the resonance enhancement effect. The ring resonator...
The authors report the bandpass-modulation characteristics of a ring resonator-based traveling-wave modulator using an electrooptic polymer AJL8/APC. The use of the traveling-wave electrode makes it possible to achieve an efficient modulation around 28 GHz, which is the free spectral range of the resonator, with a 3-dB bandwidth of 7 GHz. The modulation sensitivity is evaluated by defining an equivalent...
