Causa, F. and Burrow, L., 2007. Ripple-free high-power super-luminescent diode arrays. IEEE Journal of Quantum Electronics, 43 (11-12), pp. 1055-1059.
This paper presents the experimental and theoretical characterisation of arrays of tapered super-luminescent diodes to achieve very high, broad-band, ripple-free optical output. These arrays were fabricated from 980-nm high-power triple-quantumwell InGaAs–AlGaAs double heterostructures. Output powers of 2.7 W pulsed and of 280-mW quasi-CW were obtained from antireflection- coated arrays, with 10% maximum wall-plug efficiency per pulse at 0.75-W pulsed output power. Experimental and theoretical results for the optical-electrical characteristics and the near and far-field radiation characteristics of the arrays are discussed and compared with those of corresponding individual super-luminescent diodes.
