Integrated Nonmagnetic Optical Isolators Based on Photonic Transitions
Integrated optical isolator nonreciprocal optics photonic transition refractive index modulation
2010/8/10
Based on the effects of photonic transitions, here we show that a linear, broadband, and nonreciprocal isolator can be accomplished by spatial–temporal refractive index modulations that simultaneously...
Complete optical isolation created by indirect interband photonic transitions
optical isolation created indirect interband photonic transitions
2009/8/10
Achieving on-chip optical signal isolation is a fundamental difficulty in integrated photonics1. The need to overcome this difficulty is becoming increasingly urgent, especially with the e...
Optical isolation based on nonreciprocal phase shift induced by interband photonic transitions
Optical isolation nonreciprocal phase shift lnterband photonic transitions
2009/8/10
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...
