By tightly focusing femtosecond laser pulses, we achieve optical breakdown in a transparent material using only nanojoules of laser energy. Localized structural changes are produced in the focal volume and used for bulk micromachining. Using this technique, we fabricate single-mode optical waveguides and other photonics devices inside bulk glass.
