An optical or optoelectronic transceiver and methods of making the same are disclosed. The transceiver comprises a connector configured to receive an optical fiber array, a filter that is (i) configured to reflect first optical signals having a first wavelength and (ii) transparent to second optical signals having a second wavelength, wherein each of the first and second optical signals independently has an optical path to or from the optical fiber array, a mirror in the optical path of the second optical signals configured to reflect the second optical signals, a plurality of photodiodes configured to receive a subset of the first and/or second optical signals and generate a corresponding plurality of received electrical signals therefrom, and a plurality of laser diodes configured to transmit a remainder of the first and/or second optical signals from a corresponding plurality of transmitted electrical signals.

Optical transceiver and methods of making and using the same

An N&#xd7;N parallel optical transceiver includes a printed circuit board, a laser driving control chip, one or more lasers, two GRIN lenses, an optical band-pass filter, a multimode fiber array and a photodiode array. In the transmitter, laser beams of the same wavelength simultaneously output from the laser chip are first focused by the first GRIN lens, then the beams pass through a wavelength band-pass filter and are refocused by the second GRIN lens, and enter the channels in the multimode fiber array. In the receiver, laser beams of a different wavelength from the multimode fiber array are focused by the second GRIN lens, then reflected by the band-pass filter, refocused by the second GRIN lens, and received by the photodiode array. The multi-channel parallel transceiver has a small form, and can integrate a DFB or FP laser chip and GRIN lenses.
