Embodiment Construction

[0132] For the purpose of written description and / or claims, "refractive index" refers to the volume refractive index of a particular material (also referred to as "material refractive index") or refers to the "effective refractive index" n eff , The relationship between the latter and the propagation constant β of the specific optical mode in the specific optical element is β=2πn eff / λ. The effective refractive index can also be referred to as "mode refractive index". As explained herein, the term "low refractive index" refers to any material and / or optical structure with a refractive index less than 2.5, and "high refractive index" refers to any material and / or structure with a refractive index greater than 2.5. Within the above limits, "low refractive index" best refers to: quartz (SiO x ), germanium silicate, borosilicate, other doped quartz, and / or other silicon-based materials; silicon nitride (Si x N y ) And / or silicon oxynitride (SiO x N y ); other glass products; oth...

Abstract

An optical apparatus comprises an optical device(1910) fabricated on a substrate(1902), an external-transfer optical waveguide(1930) fabricated on the substrate and / or on the optical device, and a transmission optical waveguide. The optical device and / or the external-transfer waveguide are adapted for and positioned for transfer of optical power therebetween (end-transfer or transverse-transfer). The external-transfer waveguide and / or the transmission waveguide are adapted for transverse-transfer of optical power therebetween (mode-interference-coupled or adiabatic). The transmission waveguide is initially provided as a component mechanically separate from the substrate, device, and external-transfer waveguide. Assembly of the transmission waveguide with the substrate, device, and / or external-transfer waveguide results in relative positioning of the external-transfer waveguide and the transmission waveguide for enabling transverse-transfer of optical power therebetween. Optical power transfer between the device and the transmission waveguide through the external-transfer waveguide is thereby enabled. The transmission waveguide may preferably comprise a planar waveguide on a waveguide substrate.
