Sensors Demeter and Emcore introduce new lasers and receivers
Both new laser diode chips are based on AlGaInAs/InP MQW structures and are uncooled. The 1310 nm FP laser diode transmits over 600 m at -40 to 80ºC, while the 1310 nm DFB reaches 20 km 0 to 85 ºC. Both diode chips are available in a proprietary high-speed/low-cost TO header package with a pin photodiode for monitoring the laser output.
APD and pin receivers
The 10 Gbit/s InGaAs pin and APD receivers feature an integrated TIA, DC coupled differential output and 1000-1650 nm response in an miniature hermetically-sealed TO-46 package. The pin and APD offers -17 dBm and -23 dBm sensitivities, respectively.
Emcore adds new pin diodes for LAN and SAN applications
Emcore has added two new 1310 nm high performance pin diodes designed for use in OC-48 and OC-192 data and telecom applications. The 2.5 GHz 1 x 12 pin diode array and 10 GHz pin diode are intended to reduce costs as a result of minimal packaging requirements.
The new 12-channel InGaAs/InP pin diode array has been designed with an 80 micron aperture for easy fiber ribbon coupling in both single or multi-mode applications. The hermetic array meets Telcordia 468 standards for bare die, withstanding an environment of 85ºC and 85º RH for over 1,000 hours. The capacitance is 0.6 pf with a dark current of 0.5 nA and typical responsivity of 0.9 A/W, which supports LAN photonic switches, CATV instrumentation, datacom intermediate digital receivers, telecom short and intermediate fiber to the loop, SAN Passive Optical Networks and WDM.
The 1310 nm photodiode singlet serves the standard OC-192 for short, intermediate and long haul applications for transmission and 10 Gbps Ethernet receivers. Also designed to meet Telcordia 468 , this InGaAs/InP diode eliminates expensive hermetic package assembly and features a 32 micron aperture area.
The 2.5 GHz 1310nm 1x12 pin diode arrays are in production, and the 10GHz 1310 nm photodiode is sampling.
