“…For high-speed serial data signals, ultrafast optical switching is necessary. Several materials for optical switching have successfully been demonstrated at 640-1,280 Gb/s, materials such as highly nonlinear fibre (HNLF), periodically poled lithium niobate (PPLN), semiconductor optical amplifiers (SOAs) and chalcogenide waveguides [8,9]. In recent years, silicon has been proposed for optical switching [10].…”

In this paper, optical time division multiplexing is demonstrated using TOAD (terahertz optical asymmetric demultiplexer), which employs semiconductor optical amplifier (SOA) as nonlinear switching element. The TOAD device in its original configuration is based on Sagnac interferometer (also referred to as nonlinear optical loop mirror -NOLM).Keywords: terahertz optical asymmetric demultiplexer (TOAD), nonlinear optical loop mirror (NORM), semiconductor optical amplifier, symmetrical Mach-Zehnder (SMZ) PACS: 42.79Sz, 42.81-i

“…4 Furthermore, in optical applications, LN offers powerful electro-optical coupling as well 5 with the Y and Z cuts, and advances in use of the material continue with the application of periodically poled LN. 6 In recent years, piezoelectrically generated acoustic energy has been found to be extremely useful for microfluidics in a broad range of applications, 7,8 from atomisation for drug delivery 9,10 to fluid jetting, 11 microcentrifugation, 12 microfluidic pumping, 13 particle concentration and mixing in microdrops, 14 micro/nanoparticle generation, 15,16 biological cell manipulation, 17 and tissue engineering. 18 Because of the micrometer-order dimensions of these applications and the need for acoustic energy sources compatible with the planar geometry typical of microfabricated fluidics devices, acoustic waves in the form of surface acoustic waves (SAW) in LN at frequencies from 5 MHz to a few GHz are ideal.…”

Focused ion beam milling of microchannels in lithium niobate

We present experimental and simulation results for focused ion beam (FIB) milling of microchannels in lithium niobate in this paper. We investigate two different cuts of lithium niobate, Y-and Z-cuts, and observe that the experimental material removal rate in the FIB for both Y-cut and Z-cut samples was 0.3 lm 3 /nC, roughly two times greater than the material removal rate previously reported in the literature but in good agreement with the value we obtain from stopping and range of ions in matter (SRIM) simulations. Further, we investigate the FIB milling rate and resultant cross-sectional profile of microchannels at various ion beam currents and find that the milling rate decreases as a function of ion dose and correspondingly, the cross-sectional profiles change from rectangular to V-shaped. This indicates that material redeposition plays an important role at high ion dose or equivalently, high aspect ratio. We find that the experimental material removal rate decreases as a function of aspect ratio of the milled structures, in good agreement with our simulation results at low aspect ratio and in good agreement with the material removal rates previously reported in the literature at high aspect ratios. Our results show that it is indeed easier than previously assumed to fabricate nanochannels with low aspect ratio directly on lithium niobate using the FIB milling technique.

“…Amongst these semiconductor optical amplifiers [16,17] offer enormous nonlinearities but suffer from freecarrier dynamics at high bit-rates which translates into a significant system penalty. Periodically poled LiNbO 3 [18] has been exploited in numerous high-bit rates experiments but requires temperature control and quasi-phase matching which is not always compatible with ultrafast processing. Chalcogenide (ChG) planar waveguides, on the other hand, do not suffer free-carrier absorption, are stable at room temperature and have a broad operating bandwidth [19] due to dispersion engineering.…”

We demonstrate chip-based Tbaud optical signal processing for all-optical performance monitoring, switching and demultiplexing based on the instantaneous Kerr nonlinearity in a dispersion-engineered As(2)S(3) planar waveguide. At the Tbaud transmitter, we use a THz bandwidth radio-frequency spectrum analyzer to perform all-optical performance monitoring and to optimize the optical time division multiplexing stages as well as mitigate impairments, for example, dispersion. At the Tbaud receiver, we demonstrate error-free demultiplexing of a 1.28 Tbit/s single wavelength, return-to-zero signal to 10 Gbit/s via four-wave mixing with negligible system penalty (< 0.5 dB). Excellent performance, including high four-wave mixing conversion efficiency and no indication of an error-floor, was achieved. Our results establish the feasibility of Tbaud signal processing using compact nonlinear planar waveguides for Tbit/s Ethernet applications.
