English term or phrase: free-hole absorption
The advantages of a thinner electron injector in
accordance with this feature are twofold. First, the thinner
electron injector results in a reduction in the density of
states of the electrons in the electron injector, which causes
fewer holes to be injected into the hole injector and, subsequently, into the active QW region and thus reduces
the internal loss due to free-hole absorption. Second,
the average refractive index of the active gain region and
the injectors increases because low-index InAs/Al(In)Sb
layers now form a smaller fraction of the total active gain
region and high-index Ga(InAlAs)Sb layers form a larger
fraction, which results in better optical confinement.

neutral  Rolf Keller: "Freie Ladungsträger" können aber auch (negative) Elektronen sein. In einer Patentschrift sollte man keine Informationen weglassen. In diesem Fall also die Löcher erwähnen.
