Abstract
An electro-optical transceiver system with controlled lateral light leakage and a method of making such a system includes a plurality of emitter devices and detector devices including at least one of each, arranged in a planar array for transmitting and receiving, respectively, energy in a predetermined wavelength and a blocking medium disposed interstitially of the devices and being absorbing at the predetermined wavelength for blocking energy at the predetermined wavelength laterally leaking from an emitter device to one or more detector devices.
Claims6
A method for integration of controlled lateral light leakage photonic devices on an integrated circuit comprising:
- flip-chip bump bonding a first substrate having first photonic devices to a second substrate having second photonic devices;
- filling voids between the first and second substrate interstitially of the photonic devices with an underfill, wherein a portion of said underfill blocks a wavelength of light, and wherein said wavelength of light is that of said photonic devices;
- and
- building one or more transmissive channels in said underfill.
