Abstract:
1. A surface emitting laser diode system, comprising: first and second reflective gratings at either end of the laser, wherein the first and second reflective gratings each have a unique reflective spectrum covering a broad band of light wavelengths; and an outcoupling region between the first and second reflective gratings, wherein the outcoupling region has a grating that couples a light beam out of the laser, and wherein the outcoupling grating has a unique reflective spectrum covering a wide band of light wavelengths, wherein the reflective spectrum of the outcoupling grating comprises a second-order of the reflective spectra of the first and second reflective gratings, and a period of the outcoupling grating is selected so as to detune the reflective spectrum of the outcoupling grating away from the reflective spectra of the first and second reflective gratings, wherein an optical wavelength of the outcoupling grating is detuned by a value at which outcoupled power is phase insensitive.
