Non-reciprocal phase shift induced by an effective magnetic flux for light
Non-reciprocal phase shift induced effective magnetic
2015/8/6
Photons are neutral particles that do not interact directly with a magnetic field. However, recent theoretical work1,2 has shown that an effective magnetic field for photons can exist if t...
Optical isolation based on nonreciprocal phase shift induced by interband photonic transitions
Optical isolation nonreciprocal phase shift lnterband photonic transitions
2015/8/10
Photonic transitions in waveguides can create nonreciprocal phase response for counterpropagating modes. Such effect can be used in Mach–Zehnder interferometers to form optical isolators and circulato...
Tunable Birefringent Phase-Shift Induced in Fiber Bragg Grating by a Shape Memory Alloy Ferrule
Tunable Birefringent Phase-Shift Induced Fiber Bragg Grating Shape Memory Alloy Ferrule
2015/7/15
We present a new method to induce low loss tunable birefringent phase shifts in fiber Bragg grating by applying mechanical stresses at precise locations along the FBG with a specially designed shape m...
