High Speed Detectors

High-fidelity applications require a photonic RF signal to be cleanly converted to an electrical RF signal.

Our line of high speed fiber optic detectors facilitates the crucial conversion at a high bandwidth. Our photodetector designs offer low dark current or noise and perform with excellent responsivity.

Analog optical communication applications continue to serve markets where the expense and overhead of digital conversion are not required. High-fidelity applications require a photonic RF signal to be cleanly converted to an electrical RF signal.

Receiving and converting of high fidelity photonic signals is critical for communication systems. We offer the following products to meet the demanding customer requirements of these applications:

  • The EM169 photodetector offers bandwidth rated to a minimum of 20 GHz over the 1280–1620 nm range. This photodetector covers multiple wavelength bands with a single device, including 1310 nm, C-band, and L-band. The EM169 can handle 3 mW (5 dBm) average power with 6 mW (8 dBm) absolute maximum power, and a typical responsivity of 0.95 A/W.
  • The new EM530 photodetector further expands the product range with a dramatic increase in power handling to 50 mW (17 dBm) average and 100 mW (20 dBm) absolute maximum. The EM530 detects over the 1280-1620 nm range and features a bandwidth of 10 GHz with a typical 0.5 A/W responsivity. For a 50 mW input signal, the EM530 photodetector provides a 250 mA photocurrent level, thus increasing the level by a factor of 10 compared to the EM169 and other comparable photodetectors.
