High-Speed Traveling-Wave Electroabsorption Modulators
Electroabsorption modulators (EAMs) based on the quantum confined Stark effect in multiple quantum wells (MQWs) have advantages for high-speed, low drive voltage, and high extinction ratio applications. In this paper, a traveling-wave electrode structure is proposed to achieve high bandwidths with long devices and lower drive voltages at 1.55μm wavelength. An InGaAsP/InGaAsP MQW traveling-wave ...
متن کاملNumerical Analysis of Mushroom-type Traveling Wave Electroabsorption Modulators Using Full-Vectorial Finite Difference Method
Larger width of P-cladding layer in p-i-n waveguide of traveling wave electroabsorption modulator (TWEAM) results in lower resistance and microwave propagation loss which provides an enhanced high speed electro-optical response. In this paper, a fullvectorial finite-difference-based optical mode solver is presented to analyze mushroom-type TWEAM for the first time. In this analysis, the discont...
متن کاملAnalog Characterization of Low-Voltage MQW Traveling-Wave Electroabsorption Modulators
In this paper, high-speed traveling-wave electroabsorption modulators (TW-EAMs) with strain-compensated InGaAsP multiple quantum wells as the absorption region for analog optical links have been developed. A record-high slope efficiency of 4/V, which is equivalent to a Mach–Zehnder modulator with a of 0.37 V and a high extinction ratio of 30 dB/V have been measured. A detailed study of the nonl...
متن کاملSimultaneous Demultiplexing, Electrical Clock Recovery, and Optical Clock Generation Using Photocurrent and Subharmonic Frequency in a Traveling-wave Electroabsorption Modulator
We demonstrate for the first time using a traveling-wave electroabsorption modulator simultaneously as a photodetector, a demultiplexer, and an optical pulse generator for clock-recovery and demultiplexing at linerates of 40 Gb/s and 160 Gb/s. Introduction Compact optoelectronics components are desired to bring down the cost and ease the maintenance in high capacity optical communication system...
