- Abstract
- An optical receiver includes: an optical demultiplexer to demultiplex an optical signal in which a plurality of wavelengths is multiplexed and divide the optical signal into optical signals corresponding to the plurality of wavelengths, respectively; a reflector to change a progress direction of the divided optical signals; an optical coupling lens including, in an array form, light transmission lenses through which the divided optical signals are transmitted, respectively; a plurality of photodetectors to mount on a photodiode (PD) substrate provided on the optical coupling lens, receive the divided optical signals that are transmitted through the light transmission lenses of the optical coupling lens, respectively, and convert the received optical signals to electrical signals; and a plurality of trans impedance amplifiers provided at desired intervals to electrically connect to the plurality of photodetectors through wire bonding and amplify the received plurality of electrical signals to be a desired magnitude.
