Solsta stocking Excelitas avalanche photodiode

Excelitas InGaAs APDs provide high quantum efficiency (QE), high responsivity and low noise in the spectral range between 1000 nm and 1700 nm.

The new C30645EH-137 features Excelitas’ cutting-edge low noise performance, together with a large dV > 4 V. dV defines the span of bias voltage from Gain 10 to Breakdown.

With a large dV, customers can more easily operate the diodes at high gains > 10 over a broad temperature range while simultaneously keeping the noise low.

With their high bandwidth and low noise, the Excelitas C30645 Series helps OEMs and system manufacturers achieve cutting-edge noise specifications with optimal Signal-to-Noise Ratios (SNRs).

In particular, the new and enhanced low-noise option helps increase range and performance on LiDAR and eye-safe range-finding systems with the same laser output power.

Coherent OTDR and fibre sensing applications like DTS or DAS benefit from enhanced sensitivity on longer ranges when detecting Raman-scattered signals.
