Abstract

Discrete wavelength tuning with a heterogeneously integrated III-V/SOI sampled grating distributed feedback (SG-DFB) laser is demonstrated. The laser device is tunable over a wavelength range larger than 55 nm in wavelength steps of 5 nm and only employs two injection currents. A maximum fiber-coupled output power of -1.8 dBm is obtained as well as a high side mode suppression of more than 33 dB for all wavelength channels. The demonstrated laser is expected to find application in future flexible optical network architectures.
