Optical Interconnects (Off-chip) laser source provides light to modulator Transmitter electro-optical modulator transduces electrical data supplied from electrical driver into a modulated optical signal several high speed electro-optical modulators have been proposed that change refractive index or absorption coefficient of an optical path when an electrical signal is injected Mach-Zehnder interferometer-based silicon modulators higher modulation speeds (several GHz) large power consumption greater silicon footprint (around 10 mm) Microresonator-based P-I-N diode type modulators compact in size (10–30 mm) low power consumption low modulation speeds (several MHz) 9© 2008 Sudeep Pasricha & Nikil Dutt
