What is it about?
This paper discusses the ability of a selection of EO modulator materials and waveguide designs to increase the modulator's sensitivity by enhancing the value of the EO coefficient and reduce the half-wave voltage needed to modulate the input signal.

Why is it important?
EO phase modulator with a proper polymer material will produce better results compared to LiNbO3 in terms of length extension and low insertion loss. Furthermore, we show the performance study of an EO polymer phase modulator compared with the LiNbO3 waveguide to gain lower length extension as well low insertion loss.
Perspectives
Extensive research has been carried out to optimize the device by improving its design and making use of novel waveguide materials. This electro-optic polymer modulator is important to bio-sensing applications like as biomedical tools to measure bio-potential signal of a human body in biomedical applications
