Abstract: A first pump laser source produces a first pump optical signal at a first pump optical frequency v1P and launches it into a ring optical resonator to propagate in a forward direction around the ring optical resonator. A backscattered portion of the first pump optical signal propagates back to the first pump laser source and injection-locks it so that the first pump optical frequency v1P is locked to a first resonant mode optical frequency of the ring optical resonator. A second laser source producing a second pump optical signal at a second optical frequency v2P and can be similarly self-injection-locked to a second resonant mode optical frequency of the ring optical resonator different from the first resonant mode optical frequency.

Abstract: A tunable voltage-controlled oscillator (VCO), a dual optical-frequency reference source, an electrical reference oscillator, and an electro-optic frequency divider (eOFD) form a microwave-frequency source. The VCO generates output and modulating signals at frequency fM that is tunable over at least ±5% or more of a nominal microwave frequency. From the VCO signal at fM and output from the dual optical-frequency reference source at frequencies v1 and v2, the eOFD generates an eOFD signal at ?f=|v2?v1?n·fM| from which a loop-filtered error signal is derived, dependent on relative phase of the eOFD signal and a reference oscillator signal. The error signal is applied to the VCO to function as a phase-locked loop to stabilize the frequency fM, which can exhibit phase noise across the tuning range that is ?120 dBc/Hz+10*log10(fM/10 GHZ), or less, at 10 kHz offset frequency.

Abstract: A ring optical resonator is characterized by a Brillouin shift frequency ?a. A first pump laser source produces a first pump optical signal at a first pump optical frequency ?1P and launches it into the ring optical resonator to propagate in a forward direction around the ring optical resonator. A backscattered portion of the first pump optical signal propagates back to the first pump laser source and injection-locks it so that the first pump optical frequency ?1P is locked to a first resonant mode optical frequency of the ring optical resonator. The first pump optical signal circulating in the ring optical resonator results in a first stimulated Brillouin laser (SBL) optical signal at a first SBL optical frequency ?1=?1P??a that resonantly propagates in a backward direction around the ring optical resonator at a different resonant mode optical frequency of the ring optical resonator.

Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted.
