Abstract
A bidirectional transceiver assembly includes a VCSEL structure that emits light at a defined wavelength on a substrate structure. A photodetector receives the light. A hole structure is formed on the substrate structure to allow the light from the VCSEL structure to be emitted so as to form an optical path.
Claims31
A light emitting and receiving device comprising:
- a substrate;
- a driver element provided on the substrate that receives a voltage signal and produces an electrical signal;
- a light emitting element provided on the substrate, said light emitting element receives said electrical signal to produce emitted light;
- and
- a photodetector provided on the substrate, said photodetector having a light transmitting portion to cause light emitted by the light emitting element to pass therethrough, said light transmitting portion comprising a hole structure on said substrate to allow the emitted light from said light emitting and receiving device to be emitted so as to form an optical path, and a multilayer DBR that is deposited on the hole structure to form an optical waveguide so as to reduce optical crosstalk.
