Abstract
A technique to stabilize the effective refraction index of a laser generating system's wave guide, as well as a technique to stabilize the phase of the wave guide. In at least one embodiment of the invention, a polymer is used within the wave guide to counteract the effects of temperature on the clad material of the wave guide in order to create an overall effective refraction index that is substantially independent of temperature variations. Furthermore, in at least one embodiment of the invention relative segment lengths of the wave guide are chosen to stabilize the phase of the wave guide.

An apparatus comprising:
- a wave guide clad having an effective refraction index that is dependent upon a portion of the area of a side of a second material coplanar with and existing within a cross-section of only a portion of an optical mode surrounding a wave guide core.
An apparatus comprising:
- first means for stabilizing a light's wavelength within a wave guide, the wave guide having an effective refraction index that is dependent upon a portion of the area of a side of one of two materials coplanar with and existing within a cross-section of only a portion of an optical mode surrounding a wave guide core.
An apparatus comprising:
- first means for stabilizing a light's phase within a wave guide, the first means comprising two materials, the wave guide having an effective refraction index that is dependent upon a portion of the area of a side of one of the two materials coplanar with and existing within a cross-section of only a portion of an optical mode surrounding a wave guide core.
A system comprising:
- a light source to emit a spectrum of light wavelengths;
- a wave guide to guide light from the light source having a first wavelength, the wave guide having an effective wave guide refraction index within an optical mode of the wave guide that is independent of temperature changes in the wave guide, the effective wave guide refraction index being dependent upon a portion of the area of a side of a polymer coplanar with and existing within a cross-section of only a portion of the optical mode surrounding a wave guide core.
