Abstract
Ein Dual-Mode Ringresonator mit hoher Resonatorgüte weist einen Leitungsring (1) in Form eines Quadrates mit abgerundeten Ecken (2, 3, 4, 5) auf. Die Länge des Leitungsringes (1) ist so dimensioniert, daß der Resonator bei einer seiner ungeradzahligen Oberwellen betrieben wird. A dual-mode ring resonator with high resonator quality has a line ring (1) in the form of a square with rounded corners (2, 3, 4, 5). The length of the line ring (1) is dimensioned such that the resonator is operated at one of its odd-numbered harmonics.
