Abstract
High repetition rate stable short pulse sources play an important role in high speed optical communication systems. Besides developing a short pulse laser with very high fundamental repetition rate, the high repetition rate pulse train can also be obtained using various optical multiplication techniques, based on a Fabry-Pérot filter [1] or a fiber Bragg grating [2], for example. A more stable system may be achievable using an integrated component for multiplication. In this paper, a silicon-on-insulator (SOI) micro ring resonator with free spectral range (FSR) of 40.9 GHz at 1550 nm is used as a filter to obtain a 40 GHz pulse train. This device is compact and offers stable filtering characteristics.
