Abstract :
Summary form only given. High spectral purity, low noise semiconductor lasers are desirable for long distance telecommunication applications. We have previously reported long wavelength InGaAsP-InP triangular ring lasers operating at 1.3 μm. These ring lasers exhibit very high side-mode suppression-ratio (SMSR), that is significantly higher than FP lasers fabricated on the same chip. In general, two counter-propagating circulating laser modes can operate within the cavity, producing two separate output beams as shown. Here we report unusual ring laser relative intensity noise (RIN) behaviors for the first time
