Abstract
An optical waveguide comprises a core, an inner cladding laterally surrounding the core, and an outer cladding laterally surrounding the inner cladding, wherein the core, inner cladding, and outer cladding have a depressed well configuration. The waveguide operates in three or more wavelength bands, wherein a first wavelength band is centered at about 1300 nm, and wherein a second wavelength band is centered at about 1625 nm. The waveguide has bend losses that are less than or equal to 1.0 dB/turn when measured on a 5 mm radius bend at 1625 nm and bend losses that are less than or equal to 1.5 dB/turn when measured on a 5 mm radius bend at 1650 nm.
