Analytical Approaches to the Description of Optical Microresonator Devices

Abstract: Optical ring resonators are commonly discussed on the basis of a frequency-domain model, that divides a resonator into coupler elements, ring cavity segments, and the straight port waveguides. We look at the assumptions underlying this model and at its implications, including remarks on reciprocity/symmetry arguments, the general power transfer characteristics, the resonance condition, the spectral distance and width of the resonances, the quantities that describe the resonator performance, and a few remarks a… Show more

“…The resonance wavelength incremental change (Δλ r /Δn eff ) can be analytically estimated by using the analysis of tuning of microresonators proposed in [21]. For our slot-waveguide microring sensor the cavity mode phase propagation constant (β) in the unperturbed state (n B =n B0 , λ r =λ r0 ) can be written as:…”

“…The total ring loss comes from the imaginary part of propagation constant, bend loss of circular ring, and also from coupling between straight and circular waveguides. The resonance peaks are separated by FSR which is calculated according to equation 1 [23] as below:…”

“…In what follows, we work in the frequency-domain and limit ourselves to a linear optics setting [23]. Within this standard approach, the waveguides-coupled slotted resonator is conceptually divided into two bent-straight waveguide couplers (the boxes (I) and (II) delineated by dashed lines in Fig.…”
