Digital coherent optical systems use advanced digital signal processing and modulation techniques at the transmitter and receiver. Therefore, we begin this chapter by reviewing the fundamentals of digital communications, including principles of modulation, channel modeling, and detection. After that, we analyze the basic building blocks that make up an

Transmitter Optimized Optical Networks
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013Future optical networks will be resource limited and thus optical bandwidth and power must be used sparingly. This paper illustrates the potential network gains available by optimizing the transmitter power, constellation and DWDM channel allocations.

Optical transmittance of 3D printing materials
Applied Optics, 2021The increasing prevalence of three-dimensional (3D) printing of optical housings and mounts necessitates a better understanding of the optical properties of printing materials. This paper describes a method for using multithickness samples of 3D printing materials to measure transmittance spectra at wavelengths from 400 to 2400 nm [visible to short ...

Integrated silicon reconfigurable optical transmitter
Optics Letters, 2020We demonstrate an integrated silicon reconfigurable optical transmitter based on the reconfigurability of the Mach–Zehnder interferometer (MZI). By incorporating modulators into the tunable MZI structure and manipulating the operation states, different modulation formats, including amplitude/phase modulated binary/quaternary signals, as well as ...
