Abstract: APPARATUS AND METHOD FOR DETECTING THE POWER LEVEL IN SINGLE AND MULTI-STRIPE INTEGRATED LASERS The purpose of the present invention is to provide an apparatus for detection of a laser output on a semiconductor wafer, especially where the laser and detector are formed by similar or simultaneous processes on the same substrate. A laser cavity and a detection cavity are formed on a semiconductor wafer. The two are formed in parallel such that each has a generally axial orientation. Light emitted laterally from the laser cavity is detected by the detection cavity. The amount of light detected can then be transformed into data, which in turn can be used to control the output of the laser. Advantages of the present invention include the ability to simultaneously form the laser and detector portions, the detector portion so formed does not interfere with the beam being provided by the laser, and the ability to integrate multiple laser-sensor pairs in a semiconductor device.

Abstract: A print head (24) is disclosed for use in a marking apparatus in which a propellant stream (A) is passed through a channel (34) and directed toward a substrate (38). Marking material (28), such as ink, toner, etc., is controllably introduced into the propellant stream (A) and imparted with sufficient kinetic energy thereby to be made incident upon the substrate (38). A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials (28C, 28M, 28Y, 28K) may be introduced into the channel (34) and mixed therein prior to being made incident on the substrate (38), or mixed or superimposed on the substrate (38) without re-registration. One example is a single-pass, full-color printer.

Abstract: The optical disk unit of the present invention utilises erasable and non-erasable forms of data storage. The light reflected by the information medium 6 is directed by a polarising beam-splitting device 42 towards a data detection arrangement 40 which measures the phase difference between the components s and p of the reflected light so as to detect the magnetically recorded erasable data. Moreover, the components s and p of the reflected light are summed 52 to detect the non-erasable data.
