1. Kuan-Chou, Chen. Application of Carrier-Less Amplitude-Phase Modulation in Short-Reach Optical Interconnection and Long-Reach PONs Supplemented by Digital Signal Processing.

Degree: Master, Electro-Optical Engineering, 2015, NSYSU

In this thesis, we using high spectra efficiency and cost-effective carrier-less amplitude-phase modulation supplemented by digital signal processing in short-reach optical interconnection and long-reach passive optical network. In short-reach optical interconnection system, using novel two-mode vertical cavity surface emitting laser to extend transmission length over 1005 m OM4 fiber, using feed-forward and decision feedback equalization to substitute for frequency domain equalization. Successfully demonstrate 56 Gbps for optical back-to-back and maintain 40 Gbps high capacity after 1005 m OM4 fiber transmission. In long-reach passive optical network system, we demonstrate 4-channel wavelength division multiplexing with 24 dBm high launch power to solve the power fading phenomenon after transmission to successfully extend 3 dB bandwidth. By using electro-absorption modulation and PIN detector supplemented by nonlinear Volterra filter compensation, achieve 224 Gbps high capacity after 60 km transmission and have 12 dB power budget per wavelength which can offer 16 optical network unit and each down-stream speed > 3 Gbps.

2. Lee, Shinwook. High Power Mode-locked Semiconductor Lasers And Their Applications.

Degree: 2008, University of Central Florida

In this dissertation, a novel semiconductor mode-locked oscillator which is an extension of eXtreme Chirped Pulse Amplification (XCPA) is investigated. An eXtreme Chirped Pulse Oscillator (XCPO) implemented with a Theta cavity also based on a semiconductor gain is presented for generating more than 30ns frequency-swept pulses with more than 100pJ of pulse energy and 3.6ps compressed pulses directly from the oscillator. The XCPO shows the two distinct characteristics which are the scalability of the output energy and the mode-locked spectrum with respect to repetition rate. The laser cavity design allows for low repetition rate operation <100MHz. The cavity significantly reduces nonlinear carrier dynamics, integrated self phase modulation (SPM), and fast gain recovery in a Semiconductor optical Amplifier (SOA). Secondly, a functional device, called a Grating Coupled Surface Emitting Laser (GCSEL) is investigated. For the first time, passive and hybrid mode-locking of a GCSEL is achieved by using saturable absorption in the passive section of GCSEL. To verify the present limitation of the GCSEL for passive and hybrid mode-locking, a dispersion matched cavity is explored. In addition, a Grating Coupled surface emitting Semiconductor Optical Amplifier (GCSOA) is also investigated to achieve high energy pulse. An energy extraction experiment for GCSOA using stretched pulses generated from the colliding pulse semiconductor mode-locked laser via a chirped fiber bragg grating, which exploits the XCPA advantages is also demonstrated. Finally, passive optical cavity amplification using an enhancement cavity is presented. In order to achieve the interferometric stability, the Hänsch-Couillaud Method is employed to stabilize the passive optical cavity. The astigmatism-free optical cavity employing an acousto-optic modulator (AOM) is designed and demonstrated. In the passive optical cavity, a 7.2 of amplification factor is achieved with a 50 KHz dumping rate. Advisors/Committee Members: Delfyett, Peter.
