Abstract: A passive temperature-compensated integrated optical component having an array of adjacent waveguides, and a slab waveguide located within a groove at an intermediate section of the array. The waveguides have an index of refraction that increases with increasing temperature, and the slab waveguide has an index of refraction that decreases with increasing temperature. The slab waveguide compensates for a temperature-induced change in the refractive index of the waveguides to maintain a generally constant optical path difference between the adjacent waveguides over a temperature range.
