This paper presents an experimental study of quantum well superluminescent diodes with an extremely thin (InGa)As active layer. Under cw injection, the output power of such diodes is several milliwatts, with a centre wavelength of 830 nm and emission bandwidth of about 100 nm. © 2012 Kvantovaya Elektronika and Turpion Ltd.

A broadband light source that is based on a combination of three spectrally matched superluminescent diodes is demonstrated. The mean wavelength of the source is 1330 nm. The 3 dB spectrum width exceeds 180 nm and the 10 dB spectrum width is 220 nm. The spectral flatness is better than 2 dB and the residual spectral modulation is <0.5 dB for the whole spectral bandwidth of the source. The optical power coupled in a single-mode fibre is 4 mW. © The Institution of Engineering and Technology 2015. Source

A line of travelling-wave semiconductor optical amplifiers (SOAs) based on heterostructures used for production of broadband superluminescent diodes is developed. The pure small-signal gains of the developed SOA modules are about 25 dB, while the gain bandwidths at a level of -10 dB reach 50 - 100 nm. As a whole, the SOA modules cover the IR spectral range from 750 to 1100 nm. The SOAs demonstrate a high reliability at a single-mode fibre-coupled cw output power up to 50 mW. Examples of application of two of the developed SOA modules as active elements of broadband fast-tunable lasers are presented. © 2013 Kvantovaya Elektronika and Turpion Ltd. Source

Tunable semiconductor laser for 1025-1095 nm spectral range is developed based on the InGaAs semiconductor optical amplifier and a narrow band-pass acousto-optic tunable filter in a fiber ring cavity. Mode-hop-free sweeping with tuning speeds of up to 104 nm/s was demonstrated. Instantaneous linewidth is in the range of 0.06-0.15 nm, side-mode suppression is up to 50 dB and polarization extinction ratio exceeds 18 dB. Optical power in output single mode fiber reaches 20 mW. The laser was used in OCT system for imaging a contact lens immersed in a 0.5% intra-lipid solution. The cross-section image provided the imaging depth of more than 5mm. © 2015 SPIE. Source

Highly efficient and reliable single-mode superluminescent diodes (SLDs) with median wavelengths of 795, 840, 960 and 1060 nm and free-space output optical power (PFS) of up to 100 mW are developed. Main parameters of lighte-mitting modules based on these SLDs are presented. © 2014 IEEE. Source
