CIPRM series

In the CIPRM-1 series balanced optical receiver, Excelitas has incorporated the best features of high performance InGaAs photodiodes and a low noise, high gain transimpedance amplifier to offer a practical solution to detect small changes above the interfering noise floor of an incoming signal. The advantage is that the common optical noise is cancelled out.

This coherent InGaAs PIN balanced receiver module incorporates two low-noise photodiodes with well-matched responsivity in order to ensure a high common mode rejection ratio (CMRR). It has two single mode fibre optic inputs, an RF output, electrical supply inputs, and two photo-current monitor outputs. The CIPRM modules come in a robust casing with flange mounting holes for securing the module to working surfaces or platforms. Combined with a wide operating temperature range, the CIPRM can work in some of the toughest and harshest environments.
Key Features include:

•Spectral range - 800 - 1650nm
•200MHz bandwidth
•High performance InGaAs photodiode and TIA
•Matching responsivity
•Photo-current monitor outputs
•Rugged and robust
•RoHS compliant


•Optical delay measurement
•Heterodyne detection
•Optical coherent tomography
•Ultra low signal detection

PVG Pulsed Laser Diodes

Excelitas PVG series of high power pulsed laser diodes are multi-quantum well devices with active layers fabricated using advanced MOCVD epitaxial growth techniques.

Devices are offered housed in two convenient hermetic package configurations. The “S” style package is a TO-18 style low inductance package (~ 5.2 nH) and the “R” style is a CD 9 mm outline providing increased thermal dissipation with the option of accommodating a rear facet monitor photodiode.

This series of devices are wavelength centered at 1550 nm primarily to take advantage of a significant increase over AlGaAs and InGaAs lasers in the maximum permitted emission level with respect to Laser Institute of America or International Electrotechnical Commission (IEC) requirements.

The output wavelength of this series is well matched to the near peak spectral response of Excelitas InGaAs photodiodes types C30617H, C30618H, C30619H, C30645H and C30662H, amongst others.

Silicon Photomultipliers from Excelitas

Excelitas now offers high photon detection efficiency Silicon Photomultipliers (SiPMs) within their low light level detection portfolio.

SiPMs are arrays of parallel, interconnected avalanche photodiodes (APDs) which benefit from low-noise, low-cross-talk and ultra-fast timing resolution. Operated in a voltage range above the breakdown voltage, they provide high Photon Detection Efficiency (PDE) from near UV to NIR wavelengths. SiPMs allow multiple photons to be detected and counted within the same timeframe, and offer high linearity and high dynamic range.

One of the biggest advantages of SiPMs - as compared to traditional photomultiplier tubes (PMTs) – is their high immunity to electromagnetic fields.

Excelitas’ SiPMs are suited to high-volume applications in:

    PET Imaging

    Single Photon Emission Computed Tomography (SPECT)

    High Energy Physics

    Radiation Detection

    Fluorescence Detection

    Analytical Instrumentation
