Given that the slot critical dimension (distance between the high-index slabs or strips) is comparable to the exponential decay length of the fundamental eigenmode of the guided-wave structure, the resulting E-field normal to the high-index-contrast interfaces is enhanced in the slot and remains high across it. The power
Paper III: “Nanoimprint fabrication of slot waveguides". The author performed all the simulations and contributed to the device fabrication by doing all the nanoimprint and negative tone lithography processes. The author characterized the devices, except for the SEM imaging and AFM measurement. Paper IV: “Polymeric slot
Received 14 July 2009; accepted 6 October 2009; published online 17 November 2009. We excite a guided plasmonic mode in slot waveguides of subwavelength width. With a phase- and polarization-sensitive near-field microscope, we measure the electric field of the mode for a range of slot widths from 40 to 120 nm.

index contrast that gives rise to the slot mode, and reducing the contrast therefore weakens the slot mode character of the mode. Moreover, in sensing applications, the measured gas or liquid should interact with the air slot for maximum sensitivity. Silicon slot waveguides have already been dem- onstrated as gas detectors.
nm of the fundamental slot modes in horizontal single and multiple slot waveguides consisting of deposited amorphous silicon and silicon dioxide. The propagation loss is measured as 6.3 ±. 0.2 dB/cm and 7.0 ± 0.2 dB/cm for single and multiple slot waveguides, respectively. We also demonstrated that horizontal multiple
16 Jun 2009 Given that the width of the slot is comparable to the decay length of the field, the E-field remains high across the slot [see Figure 1(b)], resulting in a power density in the slot that is much higher than that in the high-index regions. This unique characteristic makes the slot-waveguide very attractive for
on the first measurements of low-loss waveguides that are geometrically suitable for high bandwidth slot waveguide modulators: a strip-loaded slot waveguide. Waveguide loss for undoped waveguides of 6.5 ± 0.2 dB/cm was achieved with 40 nm thick strip-loading, with the full silicon thickness around 220 nm and a slot
Using chemical vapor deposition the slot waveguide is deposited. The waveguides and the grating couplers were patterned using dry etching. The highest measured coupling efficiency is 18.5% for a 25 nm thick SiO2 slot layer. In addition to the device fabrication, development of a measurement instrument is presented.
29 Nov 2016 In this work, we present a systematic study of the slot waveguide geometries required for having zero birefringence (ZB). We show that the rail widths required for ZB are more strongly dependent on the height of the waveguide than on the slot separation. After which, we demonstrate that the ZB geometry is
