Non-reciprocal phase shift induced by an effective magnetic flux for light     Non-reciprocal  phase shift induced  effective magnetic       font style='font-size:12px;'> 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       font style='font-size:12px;'> 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       font style='font-size:12px;'> 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...
