Duobinary optical transmitter |
摘要 |
An optical transmitter for generating an optical signal includes: a precoder for coding an electrical signal of binary data; a continuous-wave (CW) light source for generating a continuous wave light; an optical phase modulator for modulating the phase of an optical signal outputted from the CW light source according to an electrical signal outputted from the precoder; a birefrigent material for bi-refracting a signal outputted from the optical phase modulator and for outputting the bi-refracted signal; and a polarizer for permitting only optical signals of a specific polarization direction to transmit therethrough when optical signals outputted from the birefrigent material are applied.
