Abstract
Optical devices and methods of fabricating thereof that include providing two different optical paths: a first optical path including a first waveguide core and a first cladding layer adjacent the first waveguide core; and a second optical path including a second waveguide core and a second cladding layer adjacent the second waveguide core. A thermo-optic coefficient (TOC) of the first waveguide core and a TOC of the first cladding layer have a same sign, for example positive, and a sign of a TOC of the second waveguide core is different than a sign of a TOC of the second cladding layer, for example, one positive and one negative. The paths may be in an Mach-Zehnder Interferometer (MZI).
