Hybrid integration of 1.3-mum transmitter and 1.55-mum reciver with fiber-embedded circuit

摘要

The high cost of manufacturing multiwavelength optical transmitter and receiver components is one of the biggest hindrances to widespread acceptance of wavelength-division multiplexing (WDM) optical subscriber loop networks for broadband multimedia systems. One proposed solution is to passively align laser diodes and photodiodes to waveguides in a circuit-like structure.~1 We have previously proposed the use of a fiber-embedded circuit for a WDM receiver module.~2 Because the fiber-embedded circuit is an in-line device, as opposed to a line-terminating device, this approach can be extended to include a passively aligned LD for the transmitter function.
