Abstract:
1. A bi-directional optoelectric transceiver module comprising: a bi-directional element with a side, a first optical axis, and a second optical axis wherein the first and second optical axes intersect approximately at the side of the bi-directional element; a reflection enhancing coating with a thickness positioned on the side of the bi-directional element wherein the reflecting enhancing coating reflects light at a first wavelength and transmits light at a second wavelength; a first lens system positioned along the first optical axis to focus light along the first optical axis; a second lens system positioned along the second optical axis to focus light along the second optical axis; a light emitting device capable of emitting light at the first wavelength along the first optical axis; a light guiding device capable of transmitting light at the second wavelength along the second optical axis and receiving light at the first wavelength along the second optical axis; and a light detecting device capable of detecting at least one of the first and second wavelengths of light along the second optical axis.
