Bent Optical Waveguide

Matteo Cherchi (Inventor), Timo Aalto (Inventor)

    Research output: PatentPatent


    An optical multi-mode HIC (high index contrast) waveguide (102, 104, 201, 301) for transporting electromagnetic radiation in the optical waveband, the waveguide comprising a guiding core portion (204) with higher refractive index, and cladding portion (206) with substantially lower refractive index configured to at least partially surround the light guiding core in the transverse direction to facilitate confining the propagating radiation within the core, the wave-guide being configured to support multiple optical modes of the propagating radiation, wherein the waveguide incorporates a bent waveguide section (202) having bend. curvature that is configured to at least gradually, preferably substantially continuously, increase towards a maximum curvature of said section from a section end.
