Performance of Capacitively Loaded RF Electrodes on SiO2/Si Substrates for High-Speed Electro-Optic Modulators
Ayed Sayem, Ting-Chen Hu, Mark Cappuzzo +3
We experimentally investigate conventional and capacitively loaded traveling-wave RF electrodes fabricated on thermally grown SiO on high-resistivity silicon substrates for hig…
Unveiling charge dynamics on the generation of high extinction wide pulse generation on thin-film lithium tantalate
Ayed Al Sayem, Shiekh Zia Uddin, Ting-Chen Hu +6
We experimentally demonstrate high-extinction optical pulse generation in thin-film lithium tantalate (TFLT), achieving a wide range of pulse widths with sharp rise and fall edges,…
Stable thin-film lithium tantalate modulators operating at high temperature for uncooled operation
Ayed Al Sayem, Shiekh Zia Uddin, Ting-Chen Hu +4
We demonstrate stable operation of a thin-film lithium tantalate (TFLT) modulator at very high operating temperatures. We show that the electro-optic modulation and bandwidth of th…
High bandwidth traveling wave electro-optic modulator at 1μm on thin-film lithium tantalate
Ayed Al Sayem, Shiekh Zia Uddin, Ting-Chen Hu +4
We present the first experimental demonstration of a high-bandwidth thin-film lithium tantalate (TFLT) electro-optic modulator operating at 1 μm, with a Vπ of 2.4 V, and less than…
High-power handling and bias stability of thin-film Lithium Tantalate microring and coupling resonators
Ayed Sayem, Shiekh Zia Uddin, Ting-Chen Hu +4
In this paper, we demonstrate the ultra-high-power handling capability and DC bias stability of optical microring and electro-optic (EO) coupling resonators on the thin-film lithiu…
A tunable FP Perot coupling interferometer on thin-film lithium niobate
Ayed Al Sayem, Heqing Huang, Ting-Chen Hu +4
We experimentally show an electro-optic tunable Fabry-Perot cavity on thin-film lithium niobate (TFLN). Instead of tuning the cavity phase and thus resonant frequency, we demonstra…
Unveiling the origins of quasi-phase matching spectral imperfections in thin-film lithium niobate frequency doublers
Jie Zhao, Xiaoting Li, Ting-Chen Hu +10
Thin-film lithium niobate (TFLN) based frequency doublers have been widely recognized as essential components for both classical and quantum optical communications. Nonetheless, th…
Ultrabroadband Polarization Insensitive Hybrid using Multiplane Light Conversion
Nicolas K. Fontaine, Yuanhang Zhang, Haoshuo Chen +10
We designed, fabricated and tested an optical hybrid that supports an octave of bandwidth (900-1800 nm) and below 4-dB insertion loss using multiplane light conversion. Measured ph…
