ABSTRACT:
An optical waveguide device comprises a plurality of mirrors, wherein at least one mirror comprises a first and second reflective end that reflect and transmit light. The plurality of mirrors comprises at least one first material having at least one first refractive index; an axis line; a first cladding comprising a second material having a second refractive index; a second cladding, formed above the first, comprising a third material having a third refractive index; a core comprising a fourth material; and a plurality of core parts formed within at least one of the first or second claddings. The fourth material has a fourth refractive index that is greater than the second and third refractive indices and the core parts have a plurality of core part ends coupled to one of the reflective ends where at least one core part end is approximately parallel to one of the reflective ends.
