96 GHz optical injection locking with a locking range of 113 MHz has been obtained from an InP/InGaAs heterojunction phototransistor oscillator IC photocoupled through the substrate by using the lightwave from a Mach-Zehnder modulator driven by double sideband modulation with suppressed carriers. Phase noise is less than -69.3 and -90.3 dBc/Hz at 10 and 100 kHz-off carrier, respectively, at around 96.4 GHz
