| 摘要 |
A semiconductor device with an integrated optical transmitter and optical receiver is disclosed that can be used in an optical subassembly. The device may include a substrate, a first component, an optical filter, and a second component, wherein the first component comprises an optical transmitter and the second component comprises an optical receiver, or vice versa. The first component can be configured to emit (or be sensitive to) a first optical signal having a first wavelength while the second component can be configured to be sensitive to (or emit) a second optical signal having a second wavelength. The optical filter can be configured to allow transmission therethrough of optical signals having the first wavelength while blocking optical signals having the second wavelength.
