DISTRIBUTED CMOS DRIVER WITH ENHANCED DRIVE VOLTAGE FOR SILICON OPTICAL PUSH-PULL MACH-ZEHNDER MODULATORS

摘要

Disclosed are structures and methods for CMOS drivers that drive silicon optical push-pull Mach-Zehnder modulators (MZMs) with twice the drive voltage per interferometer arm as with prior art designs.

主权项

1. A distributed complementary-metal-oxide-semiconductor (CMOS) driver for silicon optical modulators comprising:
a pair of diodes driven in parallel; and wherein the silicon optical modulator is electrically equivalent to a number of capacitors in series with the diodes such that a DC bias voltage is provided to the diodes.
