Download or read book High Speed Hybrid Silicon Lithium Niobate Electro Optic Modulators Related Technologies written by Peter Orlando Weigel and published by . This book was released on 2018 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electro-optic modulators (EOMs) serve as a technological pillar of the modern telecommunications industry. Without these devices, which convert electrical data into optical data through one of several physical phenomena (depending on the specific technology), telecommunications channels would be severely bandwidth-limited, particularly within data centers. To meet the ever-increasing bandwidth demands of the industry, either more EOMs are necessary (resulting in higher power requirements) or higher bandwidth EOM technology must be developed. This thesis discusses the theory, design, fabrication, and characterization of foundry-compatible hybrid silicon-lithium niobate (Si-LN) electro-optic modulators integrated on a wafer platform, a new technology with potentially far-reaching applications. By bonding a thin film of ion-sliced LN crystal, which retains the crystal properties of bulk LN, to silicon waveguides in the Mach-Zehnder modulator configuration, it is theoretically possible to exceed the bandwidth limitations of all-Si modulators without abandoning the scalable, dense silicon-on-insulator (SOI) platform. These hybrid devices make use of the favorable linear electro-optic Pockels effect of LN while using the high-index Si waveguide to reduce the optical mode area, so that low-voltage, high-bandwidth devices can be realized. This thesis focuses on developing broadband EOMs with cutoff frequencies beyond 100 GHz. Developing this technology on an SOI wafer platform fabricated via photolithography in a foundry facility presents a realistic path towards next-generation high-speed, low-power integrated EOMs.

Download or read book High speed Silicon Electro optic Modulator for Electronic Photonic Integrated Circuits written by Fuwan Gan and published by . This book was released on 2007 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: (cont.) The excellent optical and carrier confinement possible in high-index contrast waveguide devices, together with the forward biased operation and the good thermal heat sinking due to the silicon slab close to the waveguide, enables high speed modulation with small signal modulation bandwidths beyond 20GHz, a V, times length figure of merit of V, - L = 0.5Vcm and an insertion loss of about 5.3 dB. Finally, all-optical switches based on optical carrier-injection in high index contrast Si/Si02 split-ridge-waveguide (SRW) couplers are proposed. The waveguide devices are suitable for the construction of low-loss optical switch matrices as well as fast optical switching. These devices exhibit robustness against fabrication tolerances, improved heat sinking, good carrier confinement and high uniformity in transmission over the entire C-band of optical communications in contrast to comparable devices based on buried or ridge waveguides. A reasonably low electrical switching power of 1-10mW is predicted for switching frequencies in the 1MHz-1GHz range. Faster switching speed can be achieved by carrier lifetime reduction.
