“…Fig. 3 shows a schematic of the PLC along with a cross-section of the waveguide; full details regarding the device structure and its characterization can be found in [11]. The PLC takes an input signal at 10 GHz and (1) increases the repetition rate to 40 GHz and (2) allows to program the amplitude of the output pulses, namely to generate 4-bit codes which repeat at 10 GHz.…”

Reconfigurable Time Slot Interchange Based on Four-Wave Mixing and a Programmable Planar Lightwave Circuit

et al. 2014

We demonstrate the all-optical reconfigurable time slot interchange (TSI) of individual bits at 40 Gb/s based on four-wave mixing (FWM) and a programmable planar lightwave circuit (PLC). The PLC is used to generate different control signals (masks) that determine which bits undergo TSI. By programming the PLC to generate two different masks, two different TSI patterns are obtained. TSI is achieved using FWM between the data signal and the desired mask with bidirectional propagation in a length of highly nonlinear fiber. Error-free operation is obtained for both of the TSI patterns, with a power penalty G 5.2 dB, at a bit error rate of 10 À9 .

“…The 6-loop device is schematically shown on figure 12. These devices have been demonstrated by Samadi et al 2,3 for pulse repetition rate multiplication (10 to 40 GHz) and for arbitrary waveform generation. The performance of the devices was excellent, however moving towards increasingly large and complex designs requires improvements in insertion loss, power consumption and polarization dependence.…”

“…Silica planar lightwave circuit (PLC) technology was established as a convenient platform for a range of devices for WDM systems and offers low optical loss, good overlap with standard optical fibers, long term stability, and potential for hybrid integration 1 . We have recently demonstrated pulse repetition rate multiplication and arbitrary waveform generation in lattice-form MachZehnder interferometers (MZI) fabricated in silica PLC 2,3 . In this paper, the optimization of these multi-stage devices is described, through examination of the performance of the building-block structures incorporated in them.…”

The optimization of a 2x2 silica-on-silicon Mach-Zehnder interferometer (MZI) thermo-optic switch is presented. The device consists of 2 multimode interference (MMI) couplers as splitter and combiner with metal heater strips for phase control. The switching characteristics of the devices have been examined in detail as a function of several parameters. The electrical power consumption of the switch has been reduced by a factor of 2 by etching trenches alongside the waveguide heaters located on the arms of the MZI, and the polarization dependent loss has been controlled and reduced through adjustment of top cladding properties. The effect on the response time of the switch of these design changes has been investigated. Detailed characterization of the devices will be presented, and trade-offs in optimization discussed. Incorporation of these device elements into increasingly complex components for new applications in optical signal processing will be demonstrated.

“…MZI based demultiplexers can solve this problem by simultaneously filtering and delaying the optical channels with respect to their adjacent channels. In addition to this, some optical signal processing circuits require MZI based lattice filter architecture such that filter parameters can be tuned (electro-optically or thermo-optically) to generate tunable optical signals [12]. Therefore, MZI based thermally tunable wavelength demultiplexer is an important device which adds more functionalities or tunability in the low-loss Si3N4 delay waveguide based components.…”

A Thermally Tunable 1 × 4 Channel Wavelength Demultiplexer Designed on a Low-Loss Si3N4 Waveguide Platform

A thermally tunable 1 × 4 channel optical demultiplexer was designed using an ultra low-loss Si3N4 (propagation loss ~3.1 dB/m) waveguide. The demultiplexer has three 2 × 2 Mach-Zehnder interferometers (MZI), where each of the MZI contains two 2 × 2 general interference based multimode interference (MMI) couplers. The MMI couplers exhibit −3.3 dB to −3.7 dB power division ratios over a 50 nm wavelength range from 1530 nm to 1580 nm. The chrome-based (Cr) heaters placed on the delay arms of the MZI filters enable thermal tuning to control the optical phase shift in the MZI delay arms. This facilitates achieving moderately low crosstalk (14.5 dB) between the adjacent channels. The optical insertion loss of the demultiplexer per channel is between 1.5 dB to 2.2 dB over the 1550 nm to 1565 nm wavelength range. Error free performance (BER of 10 −12) is obtained for all four 40 Gb/s data rate channels. The optical demultiplexer is an important tool towards building photonic integrated circuits with complex optical signal processing functionalities in the low-loss Si3N4 waveguide platform.
