We propose and demonstrate a Mach-Zehnder type electrooptic (EO) modulator with truncated structure of the Y-junctions. The length of the branching zone is reduced to ~3 times in the proposed structure compared with the normal Y-branch structure. The symmetric and asymmetric structures of the junction are studied to consider the fabrication tolerance. We(More)
Due to the emergence of embedded applications in image and video processing, communication and cryptography, improvement of pictorial information for better human perception like de-blurring, denoising in several fields such as satellite imaging, medical imaging, mobile applications etc. are gaining importance for renewed research. Behind such developments,(More)
