“…4 shows the magnitude response of the MRR. Since the coupling coefficient between the ring and bus waveguide for TE mode is zero for this vertically integrated microring structure [8], only the TM mode shows a ring response. The Jones matrix is scanned over an 80 nm range (1525 to 1605 nm) with pm, the highest resolution of the OVA.…”

“…With the same procedure described in (2), an input SOP, , evolving to linear--polarization after passing through the input fiber is found. From (4), the Jones vector for the linear--polarization is then found as (8) Since the SOP of (8) is linear polarization, the two Jones vector components are in-phase. Thus the relative phase is found by equating two phase terms (9)…”

“…The algorithm is experimentally verified by measuring well-known devices such as a wave plate and a polarization converter. Then a microring resonator (MRR), for which the transfer function is highly dependent on input SOP [8], is analyzed as an example to demonstrate the application of the algorithm.…”

The Jones matrix measured with an optical vector analyzer (OVA) is the result of a cascade of individual Jones matrices representing the input fiber path, device under test (DUT), and output fiber path. To extract the DUT matrix, compensation of the random polarization rotation on the Poincaré sphere caused by the input and output fiber is necessary. In this letter, we present a novel algorithm that factors out the Jones matrix of the fiber pigtails and enables the DUT matrix to be resolved in a convenient reference frame. A mathematical description of the algorithm is presented and the algorithm is verified by measuring a wave plate and a polarization converter. The efficacy of the algorithm is demonstrated through characterization of a microring resonator (MRR) including round-trip loss, ring-bus coupling coefficient, and group delay of each polarization beyond the magnitude response represented by -factor.

“…To avoid substrate etching, a hybrid As 2 S 3 on Ti:LiNbO 3 platform can be used to obtain tight bending radii. Chalcogenide glasses such as arsenic trisulfide (As 2 S 3 ) have a large refractive index, allowing for tight bending radii and the fabrication of low-loss, high-Q ring resonators [2].…”

An electro-optically tunable vertically integrated As 2 S 3 Mach-Zehnder interferometer side coupled to a Ti-diffused waveguide on LiNbO 3 substrate was designed and fabricated. Asymmetric coplanar strip electrodes were placed along the As 2 S 3 path, which show strong electro-optic tuning capability, shifting the FSR of the interferometer. The tuning of the TM polarization with 7-mm-long electrodes having a 7-μm gap was observed with V π L = 15.9 V-cm, giving a tuning rate of 0.028 nm/V at 1530 nm. To our knowledge, this is the first demonstration of electro-optic tuning of an As 2 S 3 guided mode on LiNbO 3 substrate.Index Terms-Electro-optic devices, optical device fabrication, optical interferometry, tunable interferometer.
