CIP claims first 60GHz reflective electro-absorption modulator

CIP Technologies of Martlesham Heath, Ipswich, UK (which makes photonic hybrid integrated circuits and indium phosphide-based optoelectronic chips, devices, arrays and modules) has launched a combined modulation and photodetection transducer capable of working at what it claims is a record operating frequency of up to 60GHz.

The 60G-R-EAM-1550 reflective electro-absorption modulator has an insertion loss of just 3.6dB and provides digital optical modulation at 50Gb/s and RF modulation over its 60GHz bandwidth. It operates across the 1550nm C-band with a low chirp parameter, and is intended for use with a laser diode source. The photodetection capability provides 1.0A/W responsivity and 43GHz bandwidth.

CIP says that the new 60G-R-EAM-1550 meets demands for a low-insertion-loss, low-drive-voltage optical modulator in applications such as remote antennas and radio-over-fibre. The firm reckons that the device is particularly significant for those interested in the 28GHz LMDS (local multipoint distribution service) band, as well as experimental and research work in bands up to 60GHz. The combination of modulation and photodetection in a single device means that both up- and down-links can be duplexed over a single fibre, leading to significant cost reductions and capacity improvements for network operators.

The standard package with RF connectors is suitable for use with external RF components and drivers; customer-specified variants of the 60G-R-EAM-1550 can be provided on request.
