1. A planar optical device comprising:

  • a ridge-structured lower cladding layer of a first material having a first refractive index, the lower cladding layer comprising a planar portion and a ridge portion having a height H extending above the planar portion;

    a core portion of a second material overlying the ridge portion, the core portion having a thickness T, the second material having a second refractive index greater than the first refractive index; and

    a slab portion of the second material overlying the planar portion, the slab portion having a predominant thickness approximately equal to T, wherein the height H is greater than the thickness T.
