    • Among others, RF receivers based on whispering gallery mode resonators are described. In one aspect, a photonic RF device includes a laser that is tunable in response to a control signal and produces a laser beam at a laser frequency. The RF device includes a first optical resonator structured to support a whispering gallery mode circulating in the first optical resonator, the optical resonator being optically coupled to the laser to receive a portion of the laser beam into the optical resonator in the whispering gallery mode and to feed laser light in the whispering gallery mode in the optical resonator back to the laser to stabilize the laser frequency at a frequency of the whispering gallery mode and to reduce a linewidth of the laser. The RF device includes a second optical resonator made of an electro-optic material to support a whispering gallery mode circulating in the optical resonator.
    • 其中,描述了基于耳语画廊模式谐振器的RF接收机。 在一个方面,光子RF器件包括可响应于控制信号而可调谐的激光器,并产生激光频率的激光束。 RF器件包括构造成支持在第一光学谐振器中循环的耳语画廊模式的第一光学谐振器,所述光学谐振器光学耦合到激光器以在耳语画廊模式中将激光束的一部分接收到光学谐振器中,并且 将光学谐振器中的耳语画廊模式中的激光馈送到激光器,以在耳语画廊模式的频率下稳定激光频率并减少激光器的线宽。 RF装置包括由电光材料制成的第二光学谐振器,以支持在光学谐振器中循环的耳语廊模式。
