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 VÏ of 2.4 V, and less tha…
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…
AI-Driven Robotics for Optics
Shiekh Zia Uddin, Sachin Vaidya, Shrish Choudhary +5
Optics is foundational to research in many areas of science and engineering, including nanophotonics, quantum information, materials science, biomedical imaging, and metrology. How…
Programmable control of the spatiotemporal quantum noise of light
Jamison Sloan, Michael Horodynski, Shiekh Zia Uddin +6
Optoelectronic systems based on multiple modes of light can often exceed the performance of their single-mode counterparts. However, multimode nonlinear interactions often introduc…
