Abstract

A photonics device includes a silicon wafer including a cathode region, an anode region, a trench region formed between the cathode region and the anode region, and a linear ridge formed between the cathode region and the anode region. A laser diode chip is mounted on the silicon wafer. A conductor layer disposed between the silicon wafer and the laser diode chip includes a first section disposed between the laser diode chip and the cathode region on a first side of the trench to electrically connect the laser diode chip to a cathode electrode of the photonics device and a second section disposed between the anode region and the laser diode chip on a second side of the trench to electrically connect the laser diode chip to an anode electrode of the photonics device.
