"overcomes turning each laser on/ off in controlling output, by using electric fields to control how light propagates/ combines... scalable: 2.3 mm length, created using sputter vapor deposition creating films, then etched forming waveguides guiding light with trapezoidal cross-section reducing signal loss... adjusting combining sections' lengths fine-tunes each color's performance... future: reduce waveguides' surface roughness inherent using sputter method, to improve performance... barcode scanners, light show lasers"
