Abstract:
1. An optical module for receiving optical signals each having a specific wavelength different from others, comprising: a first assembly including a sub-mount, a plurality of photodiodes, and a plurality of concentrating lenses each corresponding to respective photodiodes, the sub-mount mounting the photodiodes and the concentrating lenses thereon; a second assembly including an upper base, a lower base, an optical de-multiplexer, and an optical reflector, the upper base mounting the optical de-multiplexer and the optical reflector thereon, the optical de-multiplexer de-multiplexing the optical signals depending on the specific wavelengths, the optical reflector reflecting the de-multiplexed optical signals toward the photodiodes through the respective concentrating lenses; and a housing having a bottom to install the first assembly and the second assembly thereon, wherein the sub-mount of the first assembly is directly mounted on the bottom and the upper base of the second assembly is indirectly mounted on the bottom through the lower base.
