Abstract:
A wavelength selectable laser source comprising:a pump source tunable among a plurality of pumping wavelengths .lambda..sub.p1, .lambda..sub.p2, . . . .lambda..sub.pn ;a plurality of waveguide lasers responsive to respective ones of said pumping wavelengths for emitting light at respective wavelengths .lambda..sub.s1, .lambda..sub.p2, . . . .lambda..sub.sn ; andan optical router interconnecting said pump source and said plurality of waveguide lasers so that each pump wavelength .lambda..sub.pi is directed to a respective waveguide laser responsive to said pump wavelength for emitting light at .lambda..sub.si, whereby the wavelength of laser emission is selectable by the pumping wavelength.
