Classification: CPC H  B | IPC B  H

Claim 7:
8. An optical device comprising:
a gallium and nitrogen containing surface region;
an n-type gallium and nitrogen containing cladding layer overlying the gallium and nitrogen containing surface region;
an n-side SCH layer overlying the n-type gallium and nitrogen containing cladding layer, the n-side SCH layer comprised of InGaN;
a multiple quantum well active region overlying the n-side SCH layer, the multiple quantum well active region comprised of InGaN quantum wells separated by gallium and nitrogen containing barriers;
an electron blocking layer overlying the multiple quantum well active region, the electron blocking layer comprised of AlGaN doped with magnesium;
a p-type gallium and nitrogen containing cladding layer overlying the electronic blocking layer, the p-type gallium and nitrogen containing cladding layer having a magnesium doping;
a p++—type gallium and nitrogen containing contact layer with a magnesium doping;
a laser stripe region having a first end and a second end;
a first facet provided on the first end of the laser stripe region, the first facet configured to emit light characterized by a wavelength ranging from between 390 nm to 420 nm, 420 nm to 440 nm, 440 nm to 470 nm, 470 nm to 490 nm, 490 nm to 510 nm, and 510 nm to 530 nm; and
a second facet provided on the second end of the laser stripe region.
