Where to Buy Photodetectors

Menlo Systems has developed a series of photodetectors for lowest light level signals. From avalanche to PIN photodiodes, you can find the detector that is best for your specific application. All devices are field tested in our optical frequency comb systems featuring Nobel Prize winning technology.

Analog optical communication applications continue to serve markets where the expense and overhead of digital conversion is not required. High fidelity applications require a photonic RF signal to be cleanly converted to an electrical RF signal. Gooch & Housego’s line of high speed detectors (HSD) facilitate the crucial conversion at a high bandwidth. Our photodetector designs offer low dark current or noise, and perform with excellent responsivity.

APIC analog receivers are fabricated using InP/InGaAs material platform and designed for highest responsivity, bandwidth, input optical power and maximum output current linearity. To achieve this, we use a proprietary epitaxial design and receiver configuration that allows independent optimization of the above parameters. The devices are optimized to work in RF over fiber links that require high dynamic range, low noise figure and high RF gain. The packaged components are soldered and laser welded, ensuring maximum physical reliability and performance stability with ambient temperature variation. We currently offer different configurations of receivers in the frequency range from DC to 40 GHz with a K-connector RF output. Some models include an internal 50 Ohm impedance which obviates the need for a bias T. APIC also offers a surface-mount 20-GHz PD with a 50 Ohm internal impedance.
