OSI Fibercomm Intros Custom Photodiode Housings

OSI Fibercomm (Hawthorne, CA) introduced four miniature packages for its InGaAs photodiodes for laser diode monitoring. With active area sizes of 120µm, 300µm, 400µm and 500µm, the photodiodes are low noise, have a high responsivity (1310nm to 1550nm) and operate in a spectral range from 900nm to 1,700nm. Applications include diode laser monitors, high-speed optical communications, and Gigabit/Ethernet fibre channels.

The FCI-InGaAs XXX-CCER is mounted on gull-wing ceramic substrates with glass windows that can be customized with an AR-coating. The LCER model also features gull-wing ceramic substrates. The FCI-InGaAs XXX-WCER features monitor photodiodes mounted on metallized ceramic substrates. The assemblies on the WCER are designed for easy integration. A 5-degree angled surface on the substrate of the InGaAs-XXX-ACER reduces the back reflection. All chips are mounted with low out-gassing conductive epoxy with a tolerance of ±25µm, but can also be eutectic-mounted onto the ceramic substrates.
