A plurality of linear arrays of lasers are configured into an area array by optical coupling to a linear-to-area array by optical coupling to a linear-to-area fiber optic bundle. The linear face of the bundle is coupled to the linear array of lasers. By activating all the lasers simultaneously or selectively, a single high power output or high intensity signals at discrete addresses in the area face of the bundle are achieved respectively. Applications for high power, two dimensional laser devices, high definition display, solid state laser pumping and others are achieved.

Semiconductor, light-emitting devices

An electronic scanner or printer using a fiber optic bundle and employing an initialization procedure is rendered more reliable, less expensive and provides a relatively easy path to gray scale and high resolution performance by using a unique fiber optic bundle. The bundle comprises ribbons of square fibers where the ribbons are set side by side at one end of the bundle and stacked at the other. Each square fiber of each ribbon comprises multiple rows and columns of (core) fibers each with a cladding to ensure total internal reflection of light. Gray scale is achieved by varying the exposure time and consequently the energy per pixel on a treated media or by statistically changing the amount of toner on an OPC drum creating limited apparent shades of black spots on a developed page.
