Ultrahigh-Q microwave photonic filter with tunable Q value utilizing cascaded optical-electrical feedback loops.
A microwave photonic filter with the highest reported quality factor (Q) value of 4895.31 is proposed and experimentally demonstrated by using two cascaded infinite impulse response (IIR) filters. Each IIR filter comprises both optical and electronic signals in a feedback loop and thus the loop length can be reduced without the need to consider the light coherence length. The Vernier effect ena...
متن کاملTunable bandpass microwave photonic filter with ultrahigh stopband attenuation and skirt selectivity.
we propose and demonstrate a bandpass microwave photonic filter (MPF) with ultrahigh stopband attenuation and skirt selectivity based on a simple signal cancellation technique. By injecting two phase modulated signals located on opposite sides of two resonant gain peaks of a Fabry-Pérot semiconductor optical amplifier (FP-SOA), two microwave frequency responses can be generated by the two input...
متن کاملUltrahigh-Q mechanical oscillators through optical trapping
Rapid advances are being made toward optically cooling a single mode of a micro-mechanical system to its quantum ground state and observing the quantum behavior at macroscopic scales. Reaching this regime in roomtemperature environments requires a stringent condition on the mechanical quality factor Qm and frequency fm, Qm fm & kBTbath/h, which so far has been marginally satisfied only in a sma...
متن کاملHighly Tunable Photonic Microwave Filter Based on a Broadband Optical Source Sliced by Two Cascaded Fabry-Perot Filters
In this paper we have proposed a highly tunable spectrum sliced photonic microwave band pass transversal filter for microwave and millimeterwave frequency applications. This filter configuration is based on two cascaded Fabry-Perot filters with different free spectral range and a broadband optical source. The high tunability of the filter is achieved by carefully choosing free spectral range of...
متن کاملUltrahigh-Q metallic nanocavity resonances with externally-amplified intracavity feedback
We propose a mechanism of ultrahigh-Q metallic nanocavity resonances that involves an efficient loss-compensation scheme favorable for room-temperature operation. We theoretically show that surface plasmon-polaritons excited on the entrance and exit interfaces of a metallic nanocavity array efficiently transfer external optical gain to the cavity modes by inducing resonantly-amplified intracavi...
