Silicon-nitride waveguides for on-chip Raman spectroscopy [PDF]

, 2014
The evanescent tail of the guided modes can efficiently excite Raman active molecules located in the cladding of a waveguide. Similarly, a significant fraction of the total emitted Stokes power is evanescently coupled to the same mode.

Mode Transforming Properties of Tapered Single-Mode Fiber Microlenses [PDF]

, 1993
The Gaussian approximation that is typically used to estimate single-mode fiber microlens performance is investigated. It is applied to hemispheric lenses on two types of tapered single-mode fiber. Theoretical and experimental results are compared.
