We report on a polymer-on-silicon optical bench platform that enables the hybrid integration of elemental passive and active optical functions. Planar polymer circuits are produced photolithographically, and slots are formed in them for the insertion of chips and films of a variety of materials. The polymer circuits provide interconnects, static routing elements such as couplers, taps, and multi/demultiplexers, as well as thermo-optically dynamic elements such as switches, variable optical attenuators, and tunable notch filters. Crystal-ion-sliced thin films of lithium niobate are inserted in the polymer circuit for polarization control or for electro-optic modulation. Films of yttrium iron garnet and neodymium iron boron magnets are inserted in order to magneto-optically achieve non-reciprocal operation for isolation and circulation. Indium phosphide and gallium arsenide chips are inserted for light generation, amplification, and detection, as well as wavelength conversion. The functions enabled by this multi-material platform span the range of the building blocks needed in optical circuits, while using the highest-performance material system for each function. We demonstrated complex-functionality photonic components based on this technology, including a metro ring node module and a tunable optical transmitter. The metro ring node chip includes switches, variable optical attenuators, taps, and detectors; it enables optical add/drop multiplexing, power monitoring, and automatic load balancing, and it supports shared and dedicated protection protocols in two-fiber metro ring optical networks. The tunable optical transmitter chip includes a tunable external cavity laser, an isolator, and a high-speed modulator.

High performance thermo-optic switches based on low-loss acrylate polymers

We design and fabricate digital thermo-optic switches using low-loss photocuring fluoroacrylate polymers. We use both modeling and experimental design-rule studies to elucidate the contributions to loss and cross talk of the various important building blocks that comprise a Y-branch digital optical switch (YDOS). We present the results of these studies as well as the achieved performance for 1ϫ2, 2ϫ2, and 4ϫ4 switches fabricated with these designs. Average fiber-to-fiber chip-level insertion loss (IL) values for the three designs are 1.1, 1.5, and 2.8 dB, respectively, for 1550-nm illumination. Switching times in every case are below 3 ms. Polarization-dependent loss is less than 0.1 dB at 1550 nm. Fully packaged permanently pigtailed versions of the 2ϫ2 and 4ϫ4 switches are also constructed. For these packaged devices, average insertion losses of 2.0 and 3.3 dB are achieved, and cross talk is maintained at a value less than Ϫ45 dB. Recent advances in materials performance have now allowed the insertion loss performance to be further improved, with chip-level IL being reduced to 1.0 and 2.2 dB for 2ϫ2 and 4ϫ4 switches, respectively.

“…Thus they can provide the large signal throughput and flexible network operation that will be needed in the near future. Optical switches are essential in such systems, and various types have been developed including microelectromechanical switches [1], bubble-actuated switches [2], and polymer waveguide switches [3]. Silica-based planar lightwave circuit (PLC) technology offers the advantages of a low insertion loss, mass producibility, high repeatability, and excellent long-term reliability [4] [5].…”

Solid-state optical switches using planar lightwave circuit and IC-on-PLC technologies

et al. 2005

View full text Add to dashboard Cite

We review recent progress on optical switches that employ silica-based planar lightwave circuits (PLC) including a 16 x 16 matrix switch, a 1 x 128 switch, an 8-channel 1 x 8 switch array, and a 32-channel 2 x 2 switch array. These switches are composed of silica-based waveguides and have a solid-state structure with no moving parts, thus they exhibit low insertion loss, high repeatability, and excellent long-term reliability. We also describe IC-on-PLC technology, where IC chips are integrated on the PLC surface for higher functionality and greater compactness. We report the results of reliability tests on the PLC switches, and show that they can put to practical use.
