Trends in Silicon Photonics for Fiber Optic Communication

Facebook X LinkedIn Email
As single-wavelength data rates are anticipated to approach 1 Tb/s, silicon photonics will enable the tightly coupled optics and electronics necessary for success.

CHRISTOPHER DOERR, ACACIA COMMUNICATIONS INC.

The simplest form of fiber optic communication is coupling a laser to one end of a fiber, turning the laser on and off to transmit ones and zeros, and connecting a photodetector to the other end to record the photocurrent. This simple modulation format is called on-off keying (OOK), and the reception is called direct detection. Coherent communication Besides optical power in single-mode optical fiber, phase and polarization are two additional orthogonal dimensions that can be used to transmit information. Coherent communication uses these three dimensions, increasing the...Read full article
