Theory of the Linewidth-Power Product of Photonic-Crystal Surface-Emitting Lasers

A general theory for the intrinsic (Lorentzian) linewidth of photonic–crystal surface–emitting lasers (PCSELs) is presented. The effect of spontaneous emission is modeled by a classical Langevin force entering the equation for the slowly varying waves ...

Nano‐Heterostructured TiO2‐TiO‐TiN/MoO3‐x‐Mo2N Composite LIB Anode With Enhanced Li+ Storage via Glycine‐assisted Anodization and Cathodic Deposition

Advanced Energy Materials, EarlyView.
A scalable, binder‐ and additive‐free strategy combining glycine‐assisted anodization and cathodic deposition is developed to fabricate a nano‐heterostructured composite LIB anode directly on titanium. Benefiting from its fully electrochemically active thick architecture, the anode delivers an outstanding areal capacity of 2639 µAh cm−2, nearly ...

Narrow-Linewidth Microwave Generation Using a Self-Injected DBR Laser Diode

, 2009
A novel technique for generating narrow-linewidth microwave or millimeter-wave signals is proposed. In this scheme, a delayed self-injected distributed Bragg reflector laser diode, which is tuned by a low-frequency square-wave voltage, is used to ...

Narrow linewidth fibre laser sources

, 1990
Laser sources based on rare-earth-doped single-mode optical fibres offer considerable potential as narrow-linewidth sources. Fibre laser sources have the capacity to produce highly-coherent, low-noise output, pumped by laser diodes.
