Foundry services are available to optical-component vendors to increase the density of integrated optical waveguide devices. The company offers its Hydex on 6-in. wafers with a refractive index contrast from 1.5% to 5%, with up to 10% available. This allows circuit integration densities up to 100 times greater than conventional SiO2 waveguide processes. The platform is stable through 2000 hours of high-temperature damp-heat storage tests and has low propagation loss between 1450 and 1650 nm.Little Optics, Annapolis Junction, MDwww.littleoptics.com
TO-Flix is an 850-nm, optical front-end chipset for 10 Gbit/s optical transceivers, such as XENPAK, X2, XPAK, and XFP. It is designed for very-short-reach 10-Gigabit Ethernet and Fibre Channel links in enterprise, storage area networks and local area networks. It consists of an optical receiver with a PIN photodetector and a transimpedance amplifier that convert 850-nm signals to electrical data, as well as an 850-nm VCSEL. It uses flex board interconnection, and can be used with a limiting amplifier and a laser driver amplifier.
