Optical Properties and Mode Conversion in YbPrBiGaIG Thin Film Waveguides

Generalized dispersion properties of thin-film waveguides.

EFFICIENT MODE CONVERSION IN Gd ( . 5 ^ Y ( 2 . 5 ) Ga , IRON GARNET THIN FILM WAVEGUIDES

A new method to achieve period: c reversal a of magnetization, necessaryto attain high mode conversion effIc.'encles In magneto-optic waveguides,is described. It la accomplished by .neans of a periodic permalloystructure overlaying the optical procuration path. With proper biasfields, we have observed an optimum Do conversion efficiency of (80 ±2)%at 1.15 pm in a Gd ,.Ga...

Mode conversion enables optical pulling force in photonic crystal waveguides

Thin film composite optical waveguides for sensor applications: a review.

We review the design and fabrication of thin-film composite optical waveguides (OWG) with high refractive index for sensor applications. A highly sensitive optical sensor device has been developed on the basis of thin-film, composite OWG. The thin-film OWG was deposited onto the surface of a potassium-ion-exchanged (K(+)) glass OWG by sputtering or spin coating (5-9mm wide, and with tapers at b...

Exceptional points and asymmetric mode conversion in quasi-guided dual-mode optical waveguides

Non-Hermitian systems host unconventional physical effects that be used to design new optical devices. We study a non-Hermitian system consisting of 1D planar optical waveguides with suitable amount of simultaneous gain and loss. The parameter space contains an exceptional point, which can be accessed by varying the transverse gain and loss profile. When light propagates through the waveguide s...
