Widely Tunable Integrated Laser Transmitter for Free Space Optical Communications

Integrated laser transmitters are demonstrated for free space communications. The sampled grating DBR laser is tunable from 1521 nm to 1565 nm while maintaining >45 dB side mode suppression ratio. The transmitters demonstrate a 3-dB linewidth of 6.4 MHz and 7 Gbps data rate.
