Abstract:
1. A method of making an optoelectronic circuit comprising: a. providing a first substrate; b. forming at least one dielectric waveguide in the first substrate; c. providing a second substrate having layers or islands of semiconductor material grown thereon; d. bonding an upper most layer of the second substrate onto an exposed surface of the first substrate so that the upper most layer of the second substrate is disposed over the at least one dielectric waveguide; and e. etching at least portions of the layers or islands of semiconductor material initially grown on the second substrate to define at least two active devices, the at least two active devices being physically bonded to the first substrate and optically coupled to the at least one dielectric waveguide in the first substrate, one of the at least two active devices having a different physical shape and/or size compared to another one of the at least two active devices.
