Company Profile

KBN Optics LLC is developing spectral interferometers with dramatically enhanced performance. The firm is investigating three appraoches. 1.) A hybrid interferometer: a Fabry-Perot (FP) interferometer will be placed within a MZ interferometer. The transfer characteristics of the FP mimic those of a slow-light material. This design can achieve the same sort of enhancement of sensitivity as that of a true slow-light medium placed inside the MZI. 2.) The second approach makes use of a similar analogy, but on a much smaller distance scale. This approach entails the fabrication of wavelength-scale defect resonators in an otherwise perfect photonic crystal (PhC). The design employs a sequence of such resonators each with a slightly different resonance wavelength. 3.) The third approach is to fabricate mm-scale interferometers using nano fabrication on silicon. The slow light medium is a PhC waveguide formed by a line defect in a silicon PhC structure.
