Ultra High-Speed Photodetection

This high-speed fiber optic photodetector shows flat response up to 45 GHz and is optimized for frequency-domain applications. For time-domain applications, please see our Time Domain Fiber-Optic Detectors.

Typical frequency response of Model 1014. 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.

High Sensitivity Throughout Spectrum

Model 1014 utilizes InGaAs providing coverage from 500 to 1630 nm.

Easy-to-use, Self-contained Module

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. Also, the photodetector comes equipped with a DC-bias monitor that has a transimpedance gain of 1 mV/µA and a 50-kHz bandwidth.

Singlemode FC Fiber-optic Connector Input

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 fiber-coupled input also prevents signal distortion.

Battery Powered

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.
