A novel design of a core-based rib waveguide PN junction phase shifter of length 2 mm is proposed in this paper. Two PN junctions are formed on top and bottom of the core, and improved modulation efficiency is achieved. The unbalanced MZM with this proposed phase shifter is analysed for a wavelength of 1553.5 nm with the simulation results. The permissible loss of 7.8 dB occurred in this design. At 100 Gbps, an extinction ratio of 8.15 dB and bit error rate of 3.51 × 10-6 is obtained at VπL of 1V.cm. This device can be a better choice for high-speed data rate communication applications.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
