Topological Insulators: An In‐Depth Review of Their Use in Modelocked Fiber Lasers

Noise and stability of actively modelocked fiber lasers

The timing jitter of a modelocked laser is fundamentally limited by the amplified spontaneous emission in the laser cavity. While one cannot, even in principle, remove this source of noise, one does have control over the pulse timing by using filtering and modulation. In this thesis, we report on the advances made in developing the understanding of timing jitter and stability in actively modelo...

Carrier-Envelope Phase Stabilization of Modelocked Lasers

Carrier-envelope phase stabilization of few cycle optical pulses has recently been realized. This advance in femtosecond technology is important in both extreme nonlinear optics and optical frequency metrology. The development of air-silica microstructure fiber was an enabling technology for performing phase stabilization. The microstructure fiber provides a group-velocity zero within the spect...

Plasmonics in Topological Insulators

With strong spin-orbit coupling, topological insulators have an insulating bulk state, characterized by a band gap, and a conducting surface state, characterized by a Dirac cone. Plasmons in topological insulators show high frequency-tunability in the mid-infrared and terahertz spectral regions with transverse spin oscillations, also called “spin-plasmons”. This paper presents a discussion and ...
