Infrared fibers in the 1.5um to 18um range: availability and measured properties Open
With a view towards the application in space-borne optical instruments, we first performed a world-wide market survey of infrared fibers designed for the wavelength range of 1.5 μm to 18 μm. Fiber samples purchased and tested comprise fluo…

Field distribution in the input coupling region of planar single-mode waveguides Open
We apply a numerical method for calculating the field distribution in the region immediately behind the input facet of a dielectric step-index single-mode slab waveguide. The input waves considered are focused plane waves and Gaussian beam…
