In this work we characterize the RF modulation characteristics and the dynamic range of a III-V-on-Silicon DFB laser. The direct modulation of this laser is demonstrated with a 1Gbps radio-over-fiber link at a carrier frequency up to 24 GHz using QPSK modulation. 480Mbps 64-QAM transmission at 3.5 GHz carrier frequency is demonstrated as well. In the 480 Mbps experiment both the transmitter and receiver...
We present an on-chip III–V-on-silicon mode-locked laser at 1.6 µm with a 1 GHz repetition rate and −6 dBm output in the waveguide. The optical spectrum showed a 10.8 nm wide comb, the corresponding pulses showed an autocorrelation trace FWHM of 11 ps. A high purity RF spectrum was measured.
We review the integration of III–V semiconductors on silicon photonic integrated circuits as a way of realizing fully integrated silicon photonic transceivers and short-wave infrared spectroscopic sensors.
We review our work on the heterogeneous integration of III-V laser sources on the silicon photonics platform. These building blocks enable the realization of fully integrated silicon photonic transceivers for optical interconnect applications.
