Abstract:
1. An integrated optical data transmission system comprising: an array of lasers that are modulated by a plurality of modulation signals to provide a plurality of sets of optical data signals, each of the optical data signals in each of the plurality of sets having a distinct wavelength; and a wavelength division multiplexing system to combine each of the plurality of sets of optical data signals to generate a plurality of multi-channel optical data signals that are transmitted from the integrated optical data transmission system via respective optical transmission media, wherein the wavelength division multiplexing system comprises a solid optical medium comprising a first surface to which a wavelength-division multiplexing (WDM) filter is coupled, the solid optical medium being oriented at an angle with respect to the array of lasers based on the refractive index of the solid optical medium, such that each signal of the plurality of sets of optical data signals propagates through the solid optical medium at a refracted angle selected to combine each of the plurality of sets of optical data signals by reflecting an optical data signal from a mirror coupled to a second surface of the solid optical medium spaced apart from and opposite the first surface and by reflecting the additional optical data signal from the WDM filter.
