20110235972 | SEPARATING AND COMBINING SINGLE-MODE AND MULTIMODE OPTICAL BEAMS - Techniques for combining initially separate single mode and multimode optical beams into a single “Dual Mode” fiber optic have been developed. Bi-directional propagation of two beams that are differentiated only by their mode profiles (i.e., wavefront conditions) is provided. The beams can be different wavelengths and or contain different modulation information but still share a common aperture. This method allows the use of conventional micro optics and hybrid photonic packaging techniques to produce small rugged packages suitable for use in industrial or military environments. | 09-29-2011 |

20110293215 | LOW LOSS LASER TRANSMISSION THROUGH TELESCOPES WITH MIRROR OBSCURATIONS - The invention provides micro-optical and fiber based solutions to the problem of reflective telescopes with secondary or tertiary obscurations, and further, it ameliorates secondary or tertiary obscurations in compact reflective fiber-coupled telescopes configured as optical transmitters. One solution uses a custom hollow optical fiber and lens system to generate an annular beam that would not be obscured by the telescope secondary obscuration. Another solution uses a fiber coupled micro-axicon lens assembly to achieve the same result. | 12-01-2011 |
