High Speed Detectors

High Speed Detectors (HSDs)

Analog optical communication applications continue to serve markets where the expense and overhead of digital conversion is not required. High fidelity applications require a photonic RF signal to be cleanly converted to an electrical RF signal. G&H’s line of high speed detectors (HSD) facilitate the crucial conversion at a high bandwidth. Our photodetector designs offer low dark current or noise, and perform with excellent responsivity.

Receiving and converting of high fidelity photonic signals is critical for communication systems. G&H offers two 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.

Manufactured in volume, these two HSD photodetector devices are rated for performance over the -40 to +85 °C environmental temperature conditions. Our engineers are focused on maximizing photodetector performance to enable higher power and high speed ruggedized systems for industrial, defence, medical, and scientific applications.
