Description

The 10 Gbits/s Electro-Optic Modulator is designed for long-wavelength, single-mode external amplitude mod- ulation applications. It uses an integrated Mach- Zehnder configuration to convert single polarization CW light from a semiconductor (DFB) laser into a time- varying optical output signal. Agere Systems Inc. also offers a 10 mW CW laser with polarization-maintaining fiber (D2525P) to use as a source for the modulator. The Ti-diffusion process is a standard feature on all modulator devices. The 2623N, 2623Y , and 2623CS are single-drive, 10 Gbits/s modulators; the 2623CSA is a single-drive, 10 Gbits/s modulator with an attenuat- ing section. Variable attenuation to >19 dB is achieved through a dc bias voltage. The package is hermetic to protect the LiNbO 3 die from the environment. Novel processing techniques now make it possible to achieve 20-year operation with little drift in the dc bias point. The modulator is tested to, and meets the intent of TR-NWT -00468. Other standard features include P ANDA-type polariza- tion-maintaining fiber (PMF) for the optical input (all codes) and output (2623N, 2623Y , and 2623C) fiber with FC-type connectors that are keyed to the axis of polarization. Custom designs are available. Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso- lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
