“…This is due to its sech characteristics of the soliton pulse that forms a slightly wider pulse and this will reduce the power. However, it is still about 3 orders lower than that of Kerr-type microring resonator all-optical switch [26]. Figure 8 (b) depicts the power ratio at the drop port, DP and throughput port, TP as a function of the switching power, P switch .…”

“…Such controllable switch is necessary to engineer a high performance switching in microring resonator planar waveguide structures. The relationships between the electrical field amplitudes s1, s2 , r1 , r2 and E i1 are given by these set of equations [26], [29], Here s is the microring resonator transmission coefficient or also known as the coupler reflectivity, φ is the phase shift in one circle of the ring, which can be divided into two parts: the linear part φ 0 and the nonlinear part Δφ, i.e.…”

“…In recent years, solitons have been the subject of intense theoretical and experimental studies in many different fields, including optical tweezer [21], [22], optical trapping [23], drug delivery [24], optical cryptography [25] and optical switching [26]- [28]. Since optical soliton have many advantages and is used in various of applications, it is desirable to introduce soliton in the all-optical switch.…”

One of the critical problems in achieving a real practical all-optical switching devices is the requirement for a strong material nonlinearity. A strong material nonlinearity is crucial in order to achieve a low switching power. However, silicon-based all-optical switches require extremely high switching power due to its relatively weak nonlinear optical properties. To overcome this limitation, we have designed an all-optical switch configuration based on silicon microring resonator structure and demonstrated the switching operation based on the nonlinear effects induced by a soliton pulse. The soliton pulse induces freecarrier concentration through two-photon absorption (TPA) effect and this leads to enhance the refractive index change and enhance the nonlinearity of the silicon. Thus, the silicon microring resonator alters the nonlinear phase shift which is required for switching.

“…Integrated ring resonators have found a number of usages in integrated optics due to their compact size, low cost of fabrication and their ability to integrate with on chip circuits. Today, micro-size resonators are practical devices for switching [2][3][4], multiplexing, demultiplexing [5] and wavelength filtering [6,7], modulation applications [8], wide band antenna [9,10], modulator and logic gate in optical signal processing [11,12], and sensitive sensors and biosensors [13][14][15]. One of the primary applications of ring resonators is their application as an add-drop notch type filter in optical networks.…”

In this paper, we introduced double-critical coupling condition (DCCC) for lossy mode couplers of the add-drop resonator to achieve the desirable and tunable signals required for optical communication and photonics sensors applications. The performance of add-drop resonator under double-critical condition is simulated and analyzed. Some equations were derived for optical parameters including full width at half maximum (FWHM), the out-of-band rejection ratio (OBRR), quality factor and the crosstalk of the add-drop resonator, and the output signals were examined as a function of DCCC. Based on double-critical condition, the OBRR values larger than 40 dB, the crosstalk larger than 50 dB, highest quality factor of 9000 and the FWHM as small as 0.17 nm were realized in silicon add-drop resonator, which are quite compatible with the reported experimental data. Double-critical condition shows that the lossless coupling is not enough condition to acquire high-quality filtered signal with a large crosstalk and in presence of coupling losses, the DCCC can determine the optimum relation between the strength of coupling coefficients and the coupling losses.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Optical transfer function for add-drop resonator is derived in the presence of coupling loss using the scattering matrix method. A critical coupling condition for ADR is calculated. The response of the ADR under variation of coupling losses and coupling coefficients is studied. The number of allowed states under the critical condition is determined. The full width at half maximum as sharp as 0.17 nm is achieved. It is found that the relative phase shifts of through and drop ports show the same responses under the critical coupling condition. This response emerges in a butterfly-like phase shift, which can be considered as a new evaluating factor for checking the system in critical coupling condition.Keywords Add-drop resonator Á Phase shift Á Butterfly-like phase shift of through and drop phase Á Scattering matrix method
