Features

GaAs and InGaAs Versions

Model 1580-B utilizes a GaAs diode providing wavelength coverage from 780-870 nm, with a higher sensitivity at 850 nm than the 1544 models, popular for datacom, optical sensing, imaging, LIDAR, and time-of-flight measurements. Model 1544 utilizes an InGaAs diode to provide broad spectral coverage from 500-1630 nm for singlemode fiber and 780-1630 nm for multimode fiber.

Typical Responsivity of Model 1580

Typical Responsivity of Model 1544

Ultra-clean Pulse Response

The clean response and 32 ps rise time make these devices especially well-suited for time-domain characterization of 10-Gbit/s components. The high gain and gradual, well-behaved roll-off of the frequency response also make them useful for frequency-domain measurements.

Typical Step Response of Model 1580

Typical Pulse and Step Response of Model 1544

NOTE: Pulse response measured on a 20-GHz oscilloscope with a 100-fs optical pulse. Step response calculated from pulse response.

Switchable DC-Coupled or AC-Coupled Output

The -B versions of these photoreceivers include a DC-coupled option so they give response all the way down to DC. At the touch of a switch, you can select the traditional AC-coupled output with a 10-kHz cutoff or DC-coupled mode.

Singlemode or Multimode Fiber

In Model 1544-A/B optical signal is delivered to the PIN photodiode through a 0.1 m, 9-um core singlemode fiber, while Model 1544-A/B-50 has a 50/125-µm multimode fiber and Model 1580-B comes standard with a 62.5/125-µm multimode fiber, which can accept laser light from both the 50 and 62.5 µm core fiber.

Applications

Applications for these photoreceivers include:

  • Characterizing 10-Gbit/s components, including BER testing and generating eye diagrams
  • Characterizing the frequency or time responses of pulsed lasers, modulators, and transmitters
  • Characterizing pulse propagation through dispersive optical systems
  • RIN measurements
  • Heterodyne experiments
  • Precision timing/triggering
