A distillation probe includes a conduit having a central axis. In addition, the distillation probe includes a baffle assembly disposed in the conduit. The baffle assembly includes a plurality of axially-spaced baffles positioned one-above-the-other in a stack within the conduit. Each baffle has a central axis and a radially outer surface. Each baffle includes a first recess disposed along the radially outer surface of the baffle and extending axially through the baffle. Further, each baffle includes a plurality of cooling conduits mounted to the conduit and positioned radially adjacent the conduit. The cooling conduits are configured to cool the conduit and the baffles.

Distillation probes and methods for sampling and conditioning a fluid

A grating (461) coupling the output of a semiconductor laser (410) in a semiconductor waveguide to a dielectric waveguide (451) having a core (458) which may be efficiently butt-coupled to the core of an optical fiber (470); the laser and semiconductor waveguide, coupling grating, and dielectric waveguide are integrated on a single substrate. Further, multiple lasers (410, 420, 430, 440) with differing lasing frequencies may be integrated and their outputs grating coupled into a single dielectric waveguide (450) for wavelength division multiplexing.

Integrated laser and coupled waveguide

Utilizing round optical fibers as communication channels in optical communication networks presents the problem of obtaining a high efficiency coupling between the optical fiber and the laser. A laser is made an integral part of the optical fiber channel by either diffusing active material into the optical fiber or surrounding the optical fiber with the active material. Oscillation within the active medium to produce lasing action is established by grating the optical fiber so that distributed feedback occurs.
