Loncar is a cofounder of HyperLight Corporation, a startup which was launched to commercialize integrated photonic chips based on certain innovations developed in his lab. Thin-film lithium niobate (TFLN) based traveling-wave modulators maintain simultaneously excellent performances, including large modulation bandwidth, high extinction ratio, low optical loss, and high modulation efficiency. When the EOM is driven at a modulation frequency of 600MHz much smaller than the cavity linewidth of 1.4GHz, increasing the driving power simply broadens the transmission spectrum into one with two shallow side lobes, as shown in Fig. IEEE Photonics Technol.

On the other hand, the 30-m length of the electrode is overly conservative since it covers the full length of photonic-crystal structure including the injector, mirrors, and the cavity (Figs. Silicon optical modulators. In most cases, lasers are stand-alone devices, external to the modulators, making the whole system more expensive and less stable and scalable. 29, 20882096 (1993).

Marko Lonar. Using the Lithium Niobate Modulator: Electro-Optical and Mechanical Connections Introduction The purpose of this document is to describe how to use a Lucent Technologies Lithium Niobate (LiNbO 3 ) modulator. Ultrafast electro-optic light with subcycle control. The current generation of lithium niobate modulators are bulky, expensive, limited in bandwidth and require high drive voltages, and thus are unable to reach the full potential of the material. For the application of high-speed electro-optic switching, our simulations show that the electrode-waveguide spacing can be decreased to 1.5m for an optical Q of ~5000 (corresponding to a modulation bandwidth of ~45GHz), which will improve the modulation efficiency to 2.38GHzV1 (simulation details in Methods). Here the modulator is analyzed in a dual-drive design shown in Figure 1 (where V1 = -V2). Nat. 1f. 1a). By combining thin-film lithium niobate devices with high-power lasers using an industry-friendly process, this research represents a key step towards large-scale, low-cost, and high-performance transmitter arrays and optical networks.
