Ultra high speed photodetectors
High sensitivity throughout spectrum
Easy-to-use, self-contained module
Singlemode FC fiber-optic connector
9V battery powered
40 & 45 GHz photodetectors make ultra high-speed measurements of more than 40 GHz easy. They come equipped with a DC-bias monitor that has a transimpedance gain of 1 mV/µA and a 50 kHz bandwidth. Ultra high-speed photodetector is individually tested and shipped with their own frequency-response curve.

These ultrahigh-speed photodetectors show flat response up to 45 GHz and are optimized for frequency-domain applications. For time-domain applications, we recommend our 12-ps photodetectors. Typical frequency response of the Model 1014 is shown on left. Input power was 0.45 mW at 1.06 µm. Measurement accuracy is ±1.5 dB up to 40 GHz, and ±3.5 dB from 40 to 60 GHz. Typical frequency response of Model 1004 is shown on right. Input power was 530 µW at 670 nm.
Model 1004 utilizes a GaAs diode providing wavelength coverage from 400 to 870 nm and model 1014 utilizes InGaAs providing coverage from 500 to 1630 nm.
These self-contained modules connect directly to test instruments like digital oscilloscopes, spectrum analyzers, and network analyzers for lightwave time and frequency-domain measurements. The internal housing of the high-speed models is specially designed to preserve the frequency response and phase to give true fidelity in your measurements.
These modules accept single-mode FC-fiber-optic inputs from your optical apparatus, eliminating the need for lossy and dispersive high-frequency coaxial cables.
The photodiodes are powered by an easily accessible 9V battery. The photodiode bias circuit and battery are housed in an RF-shielded case, reducing the risk of damage from excessive voltage or rough handling, and eliminating the need for expensive bias tees. The battery also eliminates an extra power cable to the module.
