Gouy phase of nonparaxial eigenmodes in a folded resonator
ثبت نشده
چکیده
We study the effect of nonparaxiality in a folded resonator by accurate measurements of the Gouy phase, as function of the mode number for mode numbers up to 1500. Our experimental method is based upon tuning the resonator close to a frequency-degenerate point. The Gouy phase shows a nonparaxial behavior that is much stronger in the folding-plane than in the perpendicular plane. Agreement with ray-tracing simulations is established and a link with aberration theory is made.

متن کاملManifestation of the Gouy phase in strongly focused, radially polarized beams.dvi
The Gouy phase, sometimes called the focal phase anomaly, is the curious effect that in the vicinity of its focus a diffracted field, compared to a non-diffracted, converging spherical wave of the same frequency, undergoes a rapid phase change by an amount of π . We theoretically investigate the phase behavior and the polarization ellipse of a strongly focused, radially polarized beam. We find ...
متن کاملGoos-Hänchen induced vector eigenmodes in a dome cavity.
We demonstrate numerically calculated electromagnetic eigenmodes of a 3D dome cavity resonator that owe their shape and character entirely to the Goos-Hänchen effect. The V-shaped modes, which have purely TE or TM polarization, are well described by a 2D billiard map with the Goos-Hänchen shift included. A phase space plot of this augmented billiard map reveals a saddle-node bifurcation; the st...
متن کاملVery Small Size ka Band 6 Bit DMTL Phase Shifter Based on Combination of Capacitor and Resonator Type Methods
Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....
متن کاملAlignment of resonant optical cavities.
When an input Gaussian beam is improperly aligned and mode-matched to a stable optical resonator, the electric field in the resonator couples to off-axis spatial eigenmodes. We show that a translation of the input axis or a mismatch of the beam waist to the resonator waist size causes a coupling of off-axis modes which is inphase with the input field. On the other hand, a tilt of the input beam...
