Diode sources for 1.0 to 1.2 µm emission

The properties of silica fibers that are potentially attractive for fiber-optic systems at wavelengths between about 1.0 and 1.2 µm are considered. The features and deficiencies of semiconductor LEDs and lasers that could be used in this wavelength range are then reviewed and compared. These sources include: Si-compensated LEDs of GaAs and InP; ternary homojunctions of (In,Ga)As, In(As,P), and Ga(As,Sb); "pseudo" III-Vs or II-VIs such as CuInSe2and CdSnP2; and heterojunction lasers and LEDs of (In,Ga)As/(In,Ga)P, Ga(As,Sb)/ (Al,Ga)(As,Sb), and (In,Ga)(As,P)/InP.
