1.3-/spl mu/m AlGaInAs strain compensated MQW-buried-heterostructure lasers for uncooled 10-gb/s operation

Strain-induced non-linear optical properties of straddling-type indium gallium aluminum arsenic/indium phosphide nanoscale-heterostructures

“…Moreover, the uncooled InGaAlAs/InP based MQW buried lasing heterostructures have shown great promise for low power-consumption operation data communication links due to their low attenuation property [7]. In addition, InGaAlAs buried lasing heterostructures emitting 1.3 μm wavelength have also exhibited good temperature characteristics for uncooled operations [8].…”

“…Such lasing heterostructures, therefore, require the use of expensive cooling devices to stabilize the temperature for lasing operation [10]. Moreover, due to the larger potential conduction band offset ratio, the InGaAlAs/InP lasing heterostructures have shown very high electron confinement factor, reduced auger recombination and reduced threshold current [7,8,[10][11][12].…”

Thermal performance of 1.55μm InGaAlAs quantum well buried heterostructure lasers

“…Recently 1.3 µm InGaAlAs BH lasers have shown good temperature characteristics for uncooled operations [2]. There are, however, relatively few reports on 1.55 µm InGaAlAs BH lasers [3][4][5][6].…”

“…Therefore such lasers require the use of expensive cooling devices to stabilise the laser operation temperature [4]. Due to the larger potential conduction band offset ratio of the InGaAlAs/InP material system of around InGaAsP/InP heterostructures, the former material system has stronger electron confinement, reduced Auger recombination and reduced threshold current [1][2][3][4][5]. Hence InGaAlAs lasers have better temperature characteristics at wavelengths between 1.3µm and 1.55µm.…”

Scatterometry measurement of ingaasp/inp grating for DFB lasers grown with MOVPE

“…DFB lasers are promising light sources for high-bit-rate fiber communication systems because of their stable longitudinal single-mode operations [1][2][3][4][5]. Stable wavelengths of DFB lasers are also required for wavelength division multiplexing (WDM) network systems [6][7][8].…”
