ABSTRACT We demonstrate a wafer-bonded silica-on-silicon planar waveguide platform with record low total propagation loss of (0.045 ± 0.04) dB/m near the free space wavelength of 1580 nm. Using coherent optical frequency domain reflectometry, we characterize the group index, fiber-to-chip coupling loss, critical bend radius, and propagation loss of these waveguides.

    • "In strip waveguides, losses are meanwhile approaching 0.2 dB/mm [21]. (Remark: In ridge waveguides with lower mode confinement losses are below 0.2 dB/mm [22] and in planar waveguides with very weak guiding even record low losses of 0.1 dB/m have been reported [23]). Phaseshifters with polymer cladding [24] and with liquid crystals [25] have been demonstrated with strip waveguides, but the large separation of the contact electrodes used for modulation, which is typically a few microns require relatively high driving voltages.

    ABSTRACT: Organic materials combined with strongly guiding silicon waveguides open the route to highly efficient electro-optical devices. Modulators based on the so-called silicon-organic hybrid (SOH) platform have only recently shown frequency responses up to 100 GHz, high-speed operation beyond 112 Gbit/s with fJ/bit power consumption. In this paper, we review the SOH platform and discuss important devices such as Mach-Zehnder and IQ-modulators based on the linear electro-optic effect. We further show liquid-crystal phase-shifters with a voltage-length product as low as VπL = 0.06 V·mm and sub-μW power consumption as required for slow optical switching or tuning optical filters and devices.

    • "Spiral DLs have been already demonstrated using silica on silicon [14], [15], indium phosphide [16], [17] and silicon on insulator [5] based technologies. The first technology is characterized by the smallest group index, around 2.0, with silicon nitride as the waveguide core [15], while for the remaining two the group index takes values around 3.7 and 4.0, respectively. It makes these two technologies more efficient, as the same value of time delay may be obtained with the use of a shorter line. "

    ABSTRACT: In this paper, we present a study of integrated optical delay lines (DLs) for application in optical time-division multiplexers. The investigated DLs are formed by spirally folded waveguides. The components were designed in a generic approach and fabricated in multi-project wafer runs on an InP-based platform. The design process and rules, together with characterization results of test structures, are discussed. Static and dynamic measurements were performed for verification of the DLs' performance in the wavelength and time domain. Additionally, a comparison between the simulation and characterization results is given, which confirms good agreement between measured and designed values.

    • "Silicon compatible on-chip optical delay lines are especially attractive as they can be seamlessly integrated with other silicon photonic devices to form an on-chip optical interconnect system or an on-chip switchable delay network (for phased array antennas). Many silicon compatible materials, including silicon itself, silica, and silicon nitride, have been investigated for integrated optical delay lines [14] [15] [16] [17] [18]. Silicon oxynitride (SiON) is a promising candidate to serve as the core material of on-chip delay lines. "

    ABSTRACT: We investigate silicon oxynitride (SiON) waveguides for long optical delay lines on a silicon chip. With the choice of a moderately low refractive index contrast, a balance can be achieved between compact waveguide cross-section and low loss. The material composition and refractive index are characterized by Rutherford backscattering spectrometry and ellipsometry. High-temperature annealing is performed after waveguide fabrication so as to simultaneously remove light absorbing bonds in the materials and smooth the sidewall roughness at the core–cladding interface. A meter-long SiON waveguide is demonstrated on a centimeter scale chip.
