Abstract:
A wavelength-variable laser outputting a predetermined wavelength of laser light includes: a quantum well active layer positioned between a p-type cladding layer and an n-type cladding layer in thickness direction; a separate confinement heterostructure layer positioned between the quantum well active layer and the n-type cladding layer; and an electric-field-distribution-control layer positioned between the separate confinement heterostructure layer and the n-type cladding layer and configured by at least two semiconductor layers having band gap energy greater than band gap energy of a barrier layer constituting the quantum well active layer.

Claim (Index 6):
The wavelength-variable laser according to  claim 5 , wherein band gap composition wavelength of GaInAsP constituting the second semiconductor layer is equal to or greater than 1 \u03bcm.
