Where to Buy Photodetectors

Menlo Systems offers 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.

CSRayzer CR2000AH-1550-70M includes a 200 μm InGaAs avalanche photodiode and a hybrid preamplifier for the use in high speed, ultra-low light detection, in laser range finding, LIDAR and free space communications.

Gentec Electro-Optics offers a great range of power detectors based on silicon or germanium photodiodes for powers up to 750 mW.

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.

Our D2250 2.2–5.0 µm single wavelength detector is super-fast (up to 10 GHz bandwidth) and ultra-sensitive (NEP of a few fW/√Hz).

Our D2250’s are based upon a new measuring paradigm where mid-infrared light is converted into visual light and then measured with conventional visual detector technology.

The D2-260 beat note detector will detect the heterodyne beat frequency of two lasers separated by 250 MHz to 9.2 GHz.
