Frequency-sweep generation by resonant self-injection locking.

چکیده
We report a novel application of self-injection locking. A diode laser is injection locked to its own frequency-shifted emission. By resonant phase modulation of the fed-back light, the laser's emission frequency is shown to swing periodically through the locking range. The laser operates as a sweep generator driven by resonant self-injection locking.

0 Theory of self phase - locked optical parametric oscillators
The plane-wave dynamics of 3ω → 2ω, ω subharmonic optical parametric oscillators containing a second harmonic generator of the idler-wave ω is analyzed analytically by using the meanfield approximation and numerically by taking into account the field propagation inside the media. The resonant χ(−3ω; 2ω, ω) : χ(−2ω;ω,ω) cascaded second-order nonlinearities induce a mutual injection-locking of th...
متن کاملOptoelectronic Oscillators for Communication Systems
We introduce and report recent developments on a novel five port optoelectronic voltage controlled oscillator consisting of a resonant tunneling diode (RTD) optical-waveguide integrated with a laser diode. The RTD-based optoelectronic oscillator (OEO) has both optical and electrical input and output ports, with the fifth port allowing voltage control. The RTD-OEO locks to reference radio-freque...
متن کاملThe Transient Behavior of LC and Ring Oscillators under External Frequency Injection
In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
متن کاملResonant photodetector for cavity- and phase-locking of squeezed state generation.
Based on the requirement of squeezed state generation, we build the phase relationship between two electronic local oscillators for the cavity- and phase-locking branches, and a 2-way 90° power splitter is adopted to satisfy the phase relationship simultaneously, which greatly simplifies the experimental setup and adjusting process. A LC parallel resonant circuit, which is composed by the inher...
متن کاملPhase-coherent all-optical frequency division by three
The properties of all-optical phase-coherent frequency division by 3, based on a self-phase-locked continuous-wave ~cw! optical parametric oscillator ~OPO!, are investigated theoretically and experimentally. The frequency to be divided is provided by a diode laser master-oscillator power-amplifier system operated at a wavelength of 812 nm and used as the pump source of the OPO. Optical self-pha...
