“…Recently, a hybrid-waveguide ring resonator was proposed to combine a strip waveguide with a slot waveguide in such a way that the figure of merit FOM=Srr/FWHM is maximized [14]. Figure 4 shows a schematic representation of this SOI ring resonator, which consists of both a strip waveguide and a slot waveguide [47,48,49,50]. This type of ring resonator has been demonstrated to have an improved figure of merit compared to more common strip or slot waveguide-based ring resonators, as it is summarized in Table 1.…”

Recent developments in optical biosensors based on integrated photonic devices are reviewed with a special emphasis on silicon-on-insulator ring resonators. The review is mainly devoted to the following aspects: (1) Principles of sensing mechanism, (2) sensor design, (3) biofunctionalization procedures for specific molecule detection and (4) system integration and measurement set-ups. The inherent challenges of implementing photonics-based biosensors to meet specific requirements of applications in medicine, food analysis, and environmental monitoring are discussed.

“…The EO response is provided by the polymer-clad. A widely used polymer system consists of the linear conjugated dye Disperse Red 1 (DR1) doped into a poly[methyl methacrylate] (PMMA) matrix [8]. It was used to demonstrate the feasibility of employing the linear [9] as well as the quadaratic EO effect in SOI slot-waveguides demonstrating its high potential for SOH photonics [4].…”

Nonlinear optical dyes doped in optical polymer matrices are widely used for electro-optical devices. Linear optical properties change with dye concentration, which leads to a change in modal properties, especially in nano-structured integrated waveguides such as silicon slot-waveguides. Here, we investigate the influence of a nonlinear optical dye on the performance of a silicon-organic hybrid slot-waveguide. A simulation study of the modal and optical confinement properties is carried out and dependence of the structural parameters of the slot-waveguide and the organic cladding material is taken into account. As cladding material, a guest-host polymer system is employed comprising the nonlinear optical dye Disperse Red 1 (DR1) doped in a poly[methyl methacrylate] (PMMA) matrix. The refractive indices of doped and undoped PMMA were deduced from ellipsometric data. We present a guideline for an optimized slot-waveguide design for the fabrication in silicon-on-insulator technology giving rise to scalable, high-performance integrated electro-optical modulators.

“…As a consequence, slot-waveguide resonators like micro-ring resonators have typically small optical quality factors (Q-factors) [3,6,10]. To overcome this deficiency a novel ring resonator concept where the ring is only partially slotted have been recently proposed [23]. This approach combines an efficient slot-waveguide phase shifter with a low loss and strongly guiding silicon strip-waveguide in the same ring resonator.…”

An approach for design optimization of the geometrical parameters of silicon-on-insulator slot-waveguides for electro-optical modulators and biosensors is presented. Theoretical investigations of field confinement factors and effective nonlinear areas for different slot-waveguide structures are critically analyzed and thoroughly calculated. With our simulation results we explain the high efficiency of electro-optical modulators and the enhanced sensitivity of biosensors compared to strip-waveguides. The influence on the effective refractive index, field confinement factor, and effective nonlinear area of the slot width and the silicon rail width were investigated.
