Abstract: An optical transmitter, an optical receiver, a method of operating the optical transmitter, and a method of operating the optical receiver are provided. The optical transmitter includes a light source configured to output laser light, an intensity modulator configured to provide a pulse signal with a predetermined period using the laser light, an in-phase and quadrature (I/Q) modulator configured to generate a coherent modulated signal applying an I/Q signal to the pulse signal with the predetermined period, and a polarization controller configured to delay one of polarization components forming the coherent modulated signal.
