Electro-Absorption Modulator Reaches 60 GHz

PHOTONICS INNOVATIONS are behind the release of a combined modulation and photodetection transducer that can work to 60 GHz. The device, dubbed the 60G-REAM- 1550, exhibits just 3.6 dB insertion loss. It provides digital optical modulation at 50 Gb/s and RF modulation over its bandwidth. In terms of photodetection, the transducer offers 1.0 A/W responsivity and 43 GHz bandwidth. The 60G-R-EAM-1550, designed for use with a laser diode source, operates within the 1550-nm band with a low chirp parameter. The combination of modulation and photodetection in a single device means that both up and downlinks can be duplexed over a single fiber. This reflective electro-absorption modulator strives to satisfy the need for a low-insertion-loss, low-drive-voltage optical modulator in applications like remote antennas and radio over fiber. It is especially suitable for the 28-GHz Local Multipoint Distribution Service (LMDS) band as well as experimental and research work in bands to 60 GHz. The standard package with RF connectors is suitable for use with external RF components and drivers.
