摘要： A compact polarization beam splitter is formed by cascading two stages of three restricted MMIs. Each MIMI is configured to set ultra compact width and length for a rectangular waveguide body to limit no more than 4 modes therein working as a polarization beam splitter in a 50 nm wavelength window around 1300 nm. Each MMI is further configured to couple an input at a first end and a TE bar output and a TM cross output at a second end of the rectangular waveguide body. The locations of the input/output waveguide ports are designated to be a distance of ⅙ of the width away from a middle line from the first end to the second end. Two second-stage MMIs have their inputs coupled to the TE bar output and the TM cross output of the first-stage MMI and provide a second-stage TE bar output and a second-stage TM cross output, respectively.

摘要： An integrated optical modulator device. The device can include a driver module coupled to an optical modulator. The optical modulator is characterized by a raised cosine transfer function. This optical modulator can be coupled to a light source and a bias control module, which is configured to apply an off-quadrature bias to the optical modulator. This bias can be accomplished by applying an inverse of the modulator transfer function to the optical modulator in order to minimize a noise variance. This compression function can result in an optimized increased top eye opening for a signal associated with the optical modulator. Furthermore, the optical modulator can be coupled to an EDFA (Erbium Doped Fiber Amplifier) that is coupled to a filter coupled an O/E (Optical-to-Electrical) receiver.

摘要： The present invention includes a linear driver for Mach-Zehnder modulator (MZM) configured in a differential form with two waveguides carrying two traveling waves. Each waveguide comprises a MZM material configured with either a single segment in 3×MZM length or two split segments with one in 2×MZM length and another one in either 1× or 2×MZM length. By coupling a DC current source supplied with a modulation voltage with each segment thereof for providing electrical modulation signal overlapping with each of the two traveling waves. The modulated traveling waves in the two waveguides then are combined in one output signal by a multimode interference coupler. By properly choosing the configuration of MZM linear segments with optional length ratios, a low power consumption MZM linear driver provides either NRZ or PAM-4 modulation scheme to the input optical signals for telecommunication through silicon photonics.
