Abstract

Jak zapewnić w Polsce rozwój konkurencyjnej, wydajnej gospodarki? Wspierać realizację projektów badawczo-rozwojowych prowadzonych wspólnie przez przedsiębiorców i naukowców, a następnie wdrożyć ich wyniki, tak aby trafiały na rynek. Dowodem na sukces takiej strategii jest wieloletnia współpraca Wojskowej Akademii Technicznej z polską spółką Vigo System S.A., produkującą detektory podczerwieni, rozpoznawalną na globalnym rynku i notowaną na warszawskim parkiecie.

Abstract

How can we make Poland's economy more competitive and productive? By supporting R&D projects pursued jointly by entrepreneurs and scientists and turning their findings into marketable products. This strategy can be very successful, as demonstrated by longstanding collaborative ties between the Military University of Technology and Vigo System S.A., a globally recognized manufacturer of infrared detectors listed on the Warsaw Stock Exchange.

Abstract

In this work we report simulation and experimental results for an MWIR HgCdTe photodetector designed by computer simulation and fabricated in a joint laboratory run by VIGO Sytems S.A. and Military University of Technology. The device is based on a modified N+pP+ heterostructure grown on 2”., epiready, semi-insulating (100) GaAs substrates in a horizontal MOCVD AIX 200 reactor.

The devices were examined by measurements of spectral and time responses as a function of a bias voltage and operating temperatures. The time response was measured with an Optical Parametric Oscillator (OPO) as the source of ~25 ps pulses of infrared radiation, tuneable in a 1.55–16 μm spectral range. Two-stage Peltier cooled devices (230 K) with a 4.1 μm cut-off wavelength were characterized by 1.6 × 1012 cm Hz1/2/W peak detectivity and < 1 ns time constant for V > 500 mV.
