UNPRECEDENTED EFFICIENCY

SPEED AND OPERATING RANGE

SSPD PRODUCT LINE

Fiber-coupled detectors that outplay similar deices

With our detectors, we can compete with established technologies such as APD and PMT, outperforming them in many specifications if not all. With SSPDs, a remarkably wide spectral range from visible to mid-IR is possible, as well as unprecedented speeds due to superconducting to normal state transitions. Being resistant to damage from optical and electrical spikes, our detectors can remain active for more than 4 weeks.

SYSTEM SETUPS

There are two available system types

Detector module

A compact module that contains a fiber-coupled detector of the desired type. Base temperature determines the final characteristics of the detector.

Closed-cycle refrigerators

Refrigerators based on the Gifford-McMahon cycle. By simply pushing a button, a base temperature of 2.2 K (0.8 K optionally) is achieved. Our cryostats can cool down up to 16 SSPDs with the required characteristics. During one cooling cycle, the system can operate continuously for up to four weeks.

CONFIGURATION

Our detectors are configured for different operation ranges and optimized for efficiency, noise, and temporal resolution, depending on the requirements of your experiment. Detectors from our company are characterized by the following modifications:

High-efficiency detectors 

The optimal combination of high system efficiency and temporal resolution, low noise, moderate bandwidth.

Low-noise detectors

The dark count rate is reduced to one per second by using variable filtering techniques. Sensors have narrower spectral responses.

Ultra-high-efficiency detectors 

Modified HED version that is operated at lower temperatures and therefore has a better performance by all parameters.

Low-jitter detectors

Temporal resolution 25 ps.

Broadband detectors

Optimized optical cavity increases the bandwidth with a moderate drop in system efficiency.

Multimode large-area detectors

  • Further configuration of detectors determines their operating range, which affects their other characteristics. Three operating ranges are available for our detectors:

Short-wave

700-1300 nm

Telecom-wave

1300-1600 nm

Long-wave

1600-2300 nm
