Abstract:
A method of integrating a chip with a topside active optical chip, the topside active optical chip comprising at least two optical laser devices, each having an active side including an optically active region, a laser cavity having a height, an optically inactive region, a bonding side opposite the active side, and a device thickness, the method comprising:bonding the optical chip to the electronic chip; applying a substrate to the active side, the substrate having a substrate thickness over the active region in the range of between a first amount and a second amount, the first amount being between a minimum lasing thickness and about ten times the height of the laser cavity, the second amount being about 100 microns; and applying an anti-reflection coating without a special patterning or distinguishing between the at least two optical laser devices and any other optical device.
