Modulators
The speed of an optical signal is dependent upon the modulator that provides the keying. For client side applications, the most common modulation technique is On-Off-Keying. In 40 and 100 Gb/s line side applications, DP-QPSK is one of the most common standards. The semiconductor device structure for modulators can be Mach-Zender Interferometer, Franz-Keldysh or ring resonator.
