An optical waveguide structure. In some embodiments, the optical waveguide structure includes a semiconductor waveguide having a waveguide ridge, and a heater. The waveguide ridge may have a varying dopant concentration across its cross-section. The heater may include a first contact and a second contact, and the waveguide structure may include a conductive path from the first contact to the second contact, the conductive path extending through a doped portion of the waveguide ridge.

Waveguide heater

An optoelectronic device, including: a rib waveguide, the rib waveguide including: a ridge portion, which includes a temperature-sensitive optically active region, and a slab portion, positioned adjacent to the ridge portion; the device further comprising a heater, disposed on top of the slab portion wherein a part of the heater closest to ridge portion is at least 2 &#x3bc;m away from the ridge portion. The device may also have a heater provided with a bottom cladding layer, and may also include various thermal insulation enhancing cavities.
