Abstract :
In this letter, we present a new simple and, therefore, low-cost two-chip concept for the fabrication of electrothermally tunable optical microcavities. Those microcavities will be applicable to tunable components for wavelength-division multiplexing systems, such as tunable filters and tunable lasers. The performance of such a microcavity is demonstrated by fabricating a tunable filter that is based on the proposed concept.
