“…11(a). But, in the case of PhC with a YAG plate, the angle of Faraday rotation is enhanced by the two photonic mirrors on both sides of the YIG layer, 15 and the transmission of the EM wave decreased in the waveguide, as seen in Fig. 11(b).…”

“…For example, PhCs made of semiconductors can change their tuning ability through the modification of solid plasma by applying an external magnetic field 10,11 or changing the temperature 12 . PhCs made with magnetic materials of ceramics like ferrite (YIG) can show tunability because of a nonlinear response to external magnetic field 13–18 . Other tunable PhCs can be formed through the lattice distortion using microelectromechanical system actuators 19 or piezoelectric constituents 20 …”

One-dimensional (1D) photonic crystals composed of a center polycrystalline yttrium iron garnet (YIG ) plate sandwiched with alternate alumina and resin plates were fabricated using stereolithography. The formed crystals showed a transmission mode of microwave in band gap as a result of resonance at the YIG plate. The transmission frequency and intensity were controlled by applying an external magnetic field. These phenomena can be explained by Faraday and Voigt effects of YIG in magnetic field. The propagation characteristics of microwaves agreed well with the calculated results using the finite element method.

“…As a result, during the past decade the use of resonant photonic-crystal (PhC) layouts has attracted a lot of interest. Magnetophotonic crystals allow to artificially enhance the intrinsic strength of the basic MO effects [7,8]; in addition, removal of time-reversal symmetry in periodic structures leads to the appearance of novel phenomena, such as frozen light [9], photonic chiral edge states [10] and one-way band gaps [11,12]. Over the last few years, an increasing number of promising miniaturized isolator (and circulator) designs using PhC effects have been reported [11,[13][14][15][16].…”

We propose a new class of compact integrated optical circulators providing a large isolation level while maintaining a straightforward technological feasibility. Their layout is based on a nonreciprocal radial Bragg cavity composed of concentric magneto-optical rings. The circulator ports are standard rib waveguides, butt-coupled to the cavity by cutting through its outer rings. The device is specifically designed for operation in a uniform external magnetic field. Using a coupled-mode description of the complete cavity/waveguide-port system, we explore the rich behaviour of cavity circulators in presence of varying levels of direct port-to-port coupling. We demonstrate numerically a strongly miniaturized two-dimensional cavity circulator, with a total footprint of less than (10λ) 2 , achieving a 20-dB isolation level at telecom frequencies over a bandwidth of 130 GHz. The device is found to be very tolerant with respect to fabrication imperfections. We finish with an outlook on three-dimensional versions of the proposed nonreciprocal cavities.

“…Magneto-optical effects such as Faraday polarization rotation and its dynamics are intensively studied in various composite and multilayered media due to their prospectives for light control applications. 1,2 The Faraday rotation enhancement can be achieved by multiple reflection interference in a thin film, 3 or a Fabry-Perot resonator with silver mirrors 4 utilizing non-reciprocity of the effect. The natural development of magneto-optical enhancement topic are magnetophotonic crystals and microcavities (MPC and MMC) with k/2-thick cavity layer (where k is operating wavelength) and distributed Bragg reflectors yielding higher quality factor together with more compact full size of the device.…”
