We demonstrate quasi-phase-matched second harmonic generation in silicon waveguides with periodically patterned p-i-n junctions using a field-induced chi((2)). A maximum efficiency of P-2 omega/P-omega(2) = 13%/W is measured and multiple signal wavelengths are shown by changing the period.
We present the design of optical phased array devices using electro-optic polymer waveguides. EO polymer phase shifters have been investigated and applied to optical phased array devices. We found support for the basi...

We present the design of optical phased array devices using electro-optic polymer waveguides. EO polymer phase shifters have been investigated and applied to optical phased array devices. We found support for the basic characteristics of OPAs theoretically and demonstrated the designed OPAs using numerical simulations.
Rib and buried channel waveguides (BCWs) made of unannealed PECVD SiO2 were studied after exposure to high humidity. Low stressed rib waveguides had lower optical throughput change, while high index difference BCWs we...

Rib and buried channel waveguides (BCWs) made of unannealed PECVD SiO2 were studied after exposure to high humidity. Low stressed rib waveguides had lower optical throughput change, while high index difference BCWs were practically unaffected.
We introduce an extremely compact magneto-optical isolator consisting of a cavity placed in the proximity of a metal-dielectric-metal plasmonic waveguide. The transmission spectra of the structure depend on the direct...

We introduce an extremely compact magneto-optical isolator consisting of a cavity placed in the proximity of a metal-dielectric-metal plasmonic waveguide. The transmission spectra of the structure depend on the direction of the incident waveguide mode.
We present a novel suspended Si waveguide approach for hybrid near-infrared and mid-infrared operation. Large waveguide cross-sections allow mid-infrared propagation, while an original corrugation yields effective sin...

We present a novel suspended Si waveguide approach for hybrid near-infrared and mid-infrared operation. Large waveguide cross-sections allow mid-infrared propagation, while an original corrugation yields effective single-mode near-infrared operation. Exploiting this concept, we demonstrated Bragg filters with 4 nm bandwidth and 40 dB rejection.
Traditionally, bulk lithium niobate has primarily been used in surface acoustic wave devices and optical modulators, with its use in optics limited primarily by the lack of a method of creating low loss, high index wa...

Traditionally, bulk lithium niobate has primarily been used in surface acoustic wave devices and optical modulators, with its use in optics limited primarily by the lack of a method of creating low loss, high index waveguides. Thin film single crystal lithium niobate-on-insulator is a promising platform for future applications in integrated optics due to the availability of a strong electro-optic effect in this material, however. We have fabricated and characterized low-loss waveguides (< 5 dB/cm), ring and racetrack resonators, and other structures in this material system that could potentially be useful in future applications.
We demonstrated biopolymer waveguides that are gradually resorbed by the tissue and used them for wound closure. The waveguides enabled a 10-fold extension of the photoactivated tissue area in comparision with convent...
