The third feature is that the relative position of the channel range to each incidence direction is tunable.…”

“…The topic of nonreciprocal optical propagation has attracted much interest because it results in the suppression of backscattering and avoided scattering [1][2][3][4][5][6][7][8] and provides the basis for designing optical isolators. Several different approaches have been explored, such as using compound cell in magnetophotonic crystals (MPCs) [1][2][3], using optical Tamm states (OTSs) in semi-infinite one-dimensional MPCs [4], or exciting Tamm plasmon polaritons (TPPs) on the interface between MPCs and conducting metal oxides [5].…”

More recently, the effect of magnetoptic phenomena on nonreciprocal resonant transmission/reflection based on a one-dimensional photonic crystal adjacent to magneto-optical (MO) metal film has been studied [6]. The nonreciprocal resonant transmission/reflection in the above study is also based on the excitation of TPPs on the interface between a PC and MO metal film.…”

“…In all of the above studies, symmetry breaking plays the crucial role in realizing these one-way phenomena. Several limitations of the above approaches might be accounted, such as the propagation loss of SPPs [5,6] and large magnetisation required, e.g., the value of the off-diagonal element of the permittivity tensor for the MO layer is taken about several times or even ten times of the real value of the off-diagonal element of the permittivity tensor for bismuth iron garnet (0.06) [1,4,5,7,8]. In [7], the MO layers in MPC1 and MPC2 are magnetised in reversal directions.…”

a Yun-Tuan Fang and Ling Han are co-first authors.Abstract: Evanescently coupled Tamm states are achieved through two magnetophotonic crystals (MPCs) with a pair of coupling prisms. At the wavelengths of coupled Tamm states, a double of nonreciprocal optical tunnelling channels is found through the transmission spectra obtained from a developed transfer matrix method. The nonreciprocal tunnelling wavelength and the interval between two nonreciprocal channels can be adjusted depending on the width of the air gap between two MPCs or the scale invariant of a PC. The nonreciprocal tunnelling is demonstrated through electromagnetic field distribution simulations based on finite element software. Such theoretical results may provide a new method to design tunable optical isolators with a double of channels.

“…Clearly the performance of the Faraday isolator is degraded but some unidirectionality is retained and a difference in temperature between black bodies A and B still emerges and Reflective non-reciprocity is also well established for example in optical circulators and ferromagnetic optical materials. The reader is directed to [4] [5] [6] [7] [8] in particular to the non-reciprocal reflective thought experiment by Zhu and Fan [4]. The above discussion applies equally to reflective non-reciprocity.…”

A Faraday isolator is shown to develop a temperature difference between its input and output, but still complies with the second law when all the heat carriers, in this case, photons are homogeneous and indistinguishable. This result is a consequence of the H-theorem which assumes homogeneity and indistinguishability of particles. However, when a thermal feedback path is added, in which heat carriers have physical properties different from the photons in the isolator, then a heterogeneous system is formed not covered by the H-theorem, and the second law is violated.

Using a 67 GHz PSA, the phase noise at divide-by-2 frequency can be measured. The phase noise of the divide-by-2 frequency of 42.665 GHz, corresponding to the locked frequency of 85.33 GHz, was measured as shown in Figure 9. The phase noise of the L-band frequency reference is also overlapped on the same graph for comparison. Phase noise at 100 kHz and 1 MHz offset is 2100.1 and 2106.2 dBc/Hz, respectively, degrading about 30 dB from the reference noise floor. Six decibel further degradation could be expected for W-band locked frequencies. The phase noise performance is strongly limited by the reference noise floor. CONCLUSIONA W-band FS is presented in this work, fabricated in a standard 65 nm CMOS process, which consists of a K-band SSPLL and a 34 W-band FM. The proposed architecture could lower the in-band phase noise from the charge pump by M 2 times compared to the conventional fundamental FS. The proposed FS dissipates a total power of 54 mW. The measured phase noise of divide-by-2 frequency is 2100.1 dBc/Hz at 100 kHz offset and 2106.2 dBc/Hz at 1 MHz offset, respectively. It covers 9.6% tuning range of 79 to 87 GHz. The total FS chip occupies about 1.48 3 0.8 mm 2 area with on-chip loop filter and pads. To the authors' knowledge, this work is the first CMOS W-band divider-less FS consisting of SSPLL and FM.
