We develop an amended ray-optics description for reflection at the curved dielectric interfaces of optical microresonators which improves the agreement with wave optics by about one order of magnitude. The corrections are separated into two contributions of similar magnitude, corresponding to ray displacement in independent quantum-phase-space directions, which can be identified with Fresnel filtering and the Goos-Hänchen shift, respectively. Hence we unify two effects which only have been…

Fresnel filtering of Gaussian beams in microcavities.

TLDR
The theory of the Fresnel filtering for a planar interface qualitatively reproduces experimental data, and a discussion is given on small deviation between the measured data and the theory.

Curvature dependence of semiclassical corrections to ray optics: How Goos-Hänchen shift and Fresnel filtering deviate from the planar case result

Ray optics is a useful tool even in the regime where, actually, full wave calculations would be appropriate. However, wave-inspired adjustments are needed to ensure the accuracy of ray-based…

Analytical Fresnel laws at generic curved interfaces

Fresnel laws, the quantitative information of the amount of light that is reflected from a planar interface in dependence on its angle of incidence, are at the core of ray optics. However, these…

Spatial coherence and optical beam shifts.

TLDR
This work investigates the issue first experimentally and finds that the degree of spatial coherence influences the angular beam shifts, while the spatial beam shifts are unaffected.

Nearly three orders of magnitude enhancement of Goos-Hanchen shift by exciting Bloch surface wave.

TLDR
Giant Goos-Hanchen shift, ~750 times of the wavelength, could enable many intriguing applications that had been less than feasible to implement before.

Analytical Fresnel laws for curved dielectric interfaces

Fresnel laws and the corresponding Fresnel reflection and transmission coefficients provide the quantitative information of the amount of reflected and transmitted (refracted) light in dependence on…

Ray picture and ray-wave correspondence in triangular microlasers

We apply ray-optical methods to dielectric optical microcavities in the shape of triangles made of low refractive index material. We find ray trajectories that maximize the intensity inside the…

Optical Microcavities of Spiral Shape: From Quantum Chaos to Directed Laser Emission

Optical microcavities are open billiards for light in which electromagnetic waves can, however, be confined by total internal reflection at dielectric boundaries. These resonators enrich the class of…

Ray model and ray-wave correspondence in coupled optical microdisks

We introduce a ray model for coupled optical microdisks in which we select coupling-efficient rays among the splitting rays. We investigate the resulting phase-space structure and report island…

Goos–Hänchen Shift from Cold and Hot Atomic Media Using Kerr Nonlinearity

We study and examine the Goos–Hänchen shifts of a propagating probe light field in a four-level tripodtype cold and hot atomic medium. The behavior of Goos–Hänchen shifts is studied in reflection and…

Fresnel laws at curved dielectric interfaces of microresonators.

TLDR
The Goos-Hänchen effect for curved light fronts at a planar interface can be adapted to provide a qualitative and quantitative extension of the ray model which explains the observed deviations from Fresnel's laws.

Multiple beam interference in a quadrupolar glass fiber.

TLDR
It is revealed that different polygonal cavity modes that are refractively output coupled in the high-curvature region of the fiber contribute to the observed far-field interference.

Optical Processes in Microcavities

Studies of optical microresonators with dimensions between 0.1 and 10 microns are now under way in a wide variety of condensed matter systems. Ideally, one can isolate a single mode of the optical…

BLOCH modes dressed by evanescent waves and the generalized Goos-Hänchen effect in photonic crystals.

TLDR
A physical interpretation is given, showing that the existence of evanescent waves near the interfaces of the photonic crystal can be considered as a generalized Goos-Hänchen effect and a renormalized isofrequency diagram is derived giving the correct direction.

Fresnel filtering in lasing emission from scarred modes of wave-chaotic optical resonators.

TLDR
Lasing emission from asymmetric resonant cavity GaN microlasers is studied and it is found that the lasing modes are concentrated on three-bounce unstable periodic ray orbits; i.e., the modes are scarred.

Husimi functions at dielectric interfaces: Inside-outside duality for optical systems and beyond

We introduce generalized Husimi functions at the interfaces of dielectric systems. Four different functions can be defined, corresponding to the incident and departing wave on both sides of the…

Direct measurement of the wigner delay associated with the goos-Hanchen effect

It is shown experimentally that the nonspecular reflection of light on an interface induces a time delay, as predicted by Wigner's scattering theory. A differential femtosecond technique is used to…

Deviation from Snell's law for beams transmitted near the critical angle: application to microcavity lasers.

We show that when a narrow beam is incident upon a dielectric interface near the critical angle for total internal reflection it will be transmitted into the far field with an angular deflection from…

Quantum chaos in optical systems: the annular billiard.

TLDR
An S-matrix approach to open optical cavities is introduced which proves very suitable for the identification of resonances of intermediate width that will be most important in future applications like optical communication devices and it is shown that the Husimi representation is a useful tool in characterizing resonances.

High-power directional emission from microlasers with chaotic resonators

TLDR
A "bow-tie"-shaped resonance is responsible for the improved performance of the lasers in the higher range of deformations, in contrast to "whispering-gallery"-type modes of circular and weakly deformed lasers.
