Effect of internal optical loss on threshold characteristics of semiconductor lasers with a quantum-confined active region

Abstract: We develop a general approach to including the internal optical loss in the description of semiconductor lasers with a quantum-confined active region. We assume that the internal absorption loss coefficient is linear in the free-carrier density in the optical confinement layer and is characterized by two parameters, the constant component and the net cross section for all absorption loss processes. We show that, in any structure where the free-carrier density does not pin in the presence of light generation, t… Show more

“…Ввиду немгновенности захвата носителей заряда из волноводной области в квантовые ямы концентрации этих носителей в волноводной области растут с уве-личением тока инжекции в режиме лазерной генера-ции [1][2][3][4]14,16]. Вследствие этого, как видно из (12), происходит увеличение внутренних оптических потерь в волноводной области лазерной структуры.…”

“…f n is the occupancy of the lower edge of the electron quantum-confinement sub-band in the QW and f p is the occupancy of the upper edge of the hole quantum-confinement sub-band in the QW. The occupancies f n and f p are not independent quantities themselves-they are expressed in terms of the 2D-carrier densities n QW and p QW as follows: 17,18 …”
