    摘要： Embodiments herein describe an optical receiver that demultiplexes a multi-wavelength optical signal into a plurality of optical signals with respective wavelengths. Stated differently, the various wavelengths in the received optical signal are separated into different optical signals with different wavelengths. In one embodiment, the optical receiver includes a plurality of optical filters that is aligned with a mirror to perform the demultiplexing function. The embodiments herein disclose optical receivers where the optical components performing the demultiplexing function using a ball lens aligned with optical filters.
