Abstract
An optical or optoelectronic receiver and module, and methods of making and using the same, are disclosed. The receiver includes a photodetector, a first microelectromechanical device configured to reflect a multi-wavelength optical signal, a thin film filter configured to receive the multi-wavelength optical signal reflected by the first microelectromechanical device and separate a single-wavelength optical signal from the multi-wavelength optical signal, a first lens configured to focus the single-wavelength optical signal on the photodetector, and a second microelectromechanical device configured to reflect the single-wavelength optical signal towards the first lens. Each wavelength of the multi-wavelength optical signal represents or corresponds to a unique channel over which the receiver receives optical signals. The present receiver and methods enable low-cost, high-volume manufacturing of multi-channel optical or optoelectronic receivers.
