Advances in Lasers on a Chip
Researchers are working to perfect tunable dye lasers that are incorporated into microfluidic chips.
by Nancy D. Lamontagne and Breck Hitz
Microfluidic technology has miniaturized many instruments used in biotechnology and medicine into devices about the size of a microscope slide. Developers of these devices, commonly called labs on a chip or biochips, want to achieve maximum miniaturization by incorporating as much as possible, including lasers and optics, directly onto the chip, and they want the devices to require a minimum amount of external power for maximum portability. Such devices could be useful in remote locations or right in a doctor's office.
On-chip lasers must be easily and quickly tunable to allow spectroscopy or excitation at different wavelengths...
