Abstract
We develop photonic funnels, structures that provide efficient optical coupling between nano- and micro-worlds. The funnels represent conical waveguides with highly anisotropic cores and highly conductive cladding that have one opening with crossection of the order of free space wavelength and the second opening with deep subwavelength crossection. We fabricate all-semiconductor photonic funnels at mid-infrared frequency range and demonstrate, theoretically and experimentally, efficient confinement of mid-infrared light to wavelength/30 areas. Theoretically, we predict efficient out-coupling of light from ultra-small areas to diffraction-limited domain.
