We report on the fabrication of optical channel waveguide on a high-energy-beam sensitive glass using a maskless non-photolithographic processing technique. Laser direct writing and one-step chemical etching result in high quality channel waveguide with a propagation loss of about -0.27 dB/cm at 1550-nm wavelength.
