Composite Cavity Fiber Laser with Asymmetric Output Intensity and Wavelength
The composite cavity fiber laser (CCFL) is relatively simple in its fabrication, as it is essentially three wavelength matched Bragg gratings in a section of doped fiber. By using internal feedback with unequal sub-cavity lengths, unidirectional CCFLs with significantly asymmetric output power from its two outputs can be achieved. Preliminary results also show that it is possible for the lasing...
متن کاملMMI filters configuration for dual-wavelength generation in a ring cavity erbium-doped fibre laser
Background: Dual wavelength laser generation has been of constant interest due to their applications in optical communications and teraheartz generation. A novel configuration for Dual-wavelength laser generation based on the use of a couple of multimode interference (MMI) filters is demonstrated in a ring cavity Erbium-doped fibre laser. Methods: The MMI filters consist of a segment of no-core...
متن کاملTurbulence hierarchy in a random fibre laser
Turbulence is a challenging feature common to a wide range of complex phenomena. Random fibre lasers are a special class of lasers in which the feedback arises from multiple scattering in a one-dimensional disordered cavity-less medium. Here we report on statistical signatures of turbulence in the distribution of intensity fluctuations in a continuous-wave-pumped erbium-based random fibre laser...
متن کاملWideband-tuneable, nanotube mode-locked, fibre laser.
Ultrashort-pulse lasers with spectral tuning capability have widespread applications in fields such as spectroscopy, biomedical research and telecommunications. Mode-locked fibre lasers are convenient and powerful sources of ultrashort pulses, and the inclusion of a broadband saturable absorber as a passive optical switch inside the laser cavity may offer tuneability over a range of wavelengths...
متن کاملWearable Dual-Band Stripline-Fed Half-Mode Substrate-Integrated Cavity Antenna
A low-profile dual-band half-mode substrate-integrated cavity antenna with a fully shielded textile feeding mechanism is presented for wearable applications. The antenna operates at the lower and upper microwave industrial, scientific and medical (ISM) bands. The cavity geometry is accurately defined with conducting thread through computerized embroidery. Design guidelines are developed for a p...
