We report on the performance of a silicon photonic integrated circuit for laser frequency chirping, developed for FMCW LIDAR applications. An external laser source is fiber coupled to the photonic circuit and frequency chirping is achieved with a silicon IQ modulator and a monolithically integrated III-V/Si semiconductor optical amplifier to compensate for IQ modulator losses. A chirp distortion of 1.8% over 5% to 95% of the chirp ramp period was measured with a delayed selfheterodyne interferometric method. The high chirp linearity of our circuit is confirmed by FMCW ranging measurements using 2-18 m long fiber delay lines. The resulting beat frequency follows a linear dependency with the fiber delay line length (R²=0.999).

40GBaud PAM4 silicon Mach-Zehnder modulator boosted by a heterogeneously integrated SOA with 10dB-gain

Abstract: We report a silicon IQ modulator integrated with a III-V/Si semiconductor optical amplifier (SOA) at the output. We demonstrate 40GBaud PAM4 operation of one of the Mach Zehnder modulators with an SOA gain of 10dB.
