| 英文摘要 | A wavelength division multiplexing (WDM) module for transmitting and/or receiving multiple signals simultaneously includes an array of vertical cavity surface emitting lasers (VCSELs) and/or photodetectors, respectively. In the transmitter case, different VCSELs are operated at different wavelengths that change depending on a value of a condition such as temperature and/or one or more other parameters. Multiple VCSELs are assigned to each channel of the WDM. The currently active VCSEL is switched to a different VCSEL assigned to a same channel and preferably having an operating wavelength that is closer to the signal wavelength at the current measured or estimated temperature and/or other parameter value. Multiple photodetectors are assigned to each channel of the WDM, and currently active detector is switched to the second detector within the same channel. A tuning layer and a resonant waveguide grating coupler are preferably integrated into the resonant structure of the VCSEL array and wavelength specific detector array. |
