Optical waveguides are far more than mere connecting elements in integrated optical
systems and circuits. Benefiting from their high optical confinement and miniaturized …

Since the discovery that tightly focused femtosecond laser pulses can induce a highly
localised and permanent refractive index modification in a large number of transparent …

In the past few decades, several methods concerning optical thin films have been
established to facilitate the development of integrated optics. This paper provides a brief …

Fused silica glass, with its large transparency range, low thermal expansion, high resistance
to optical damage, high refractive index homogeneity, and ease of finishing has found use …

Over the last years, there has been tremendous progress with compact pulsed lasers based
on various solid-state gain media, such as crystals and glasses doped with laser-active ions …

The intentional inclusion of key atomic elements in a purpose designed glass helps to
achieve unprecedented control over the ultrafast laser written circular waveguide …

Three dimensional waveguides within the bulk of diamond are manufactured using ultrafast
laser fabrication. High intensities within the focal volume of the laser cause breakdown of the …

We report on the fabrication of, to the best of our knowledge, the first highly reflective fiber
Bragg gratings for the 4 µm wavelength range. A second-order grating with a coupling …

We compare and contrast novel techniques for the fabrication of chirped broadband fiber
Bragg gratings by ultrafast laser inscription. These methods enable the inscription of …

We present straight and s-curve waveguides in polymers fabricated by femtosecond laser
writing. A number of parallel tracks are written inside the bulk material with a well-defined …
