Abstract
A laser assembly including a silicon base and method are provided for assembling lasers on a platform in a reliable, low cost process that is suitable for high volume production. The platform can be a monolithic silicon base which has high thermal conductivity, a low coefficient of thermal expansion, and whose features can be formed with close tolerances in a low cost, reliable manner. Materials with similar coefficients of thermal expansion are used in order to maintain alignment during unexpected heating and cooling. Furthermore, a method is described that substantially eliminates the need for adhesives to bond laser components to a platform. The resultant laser can be very robust, stable, and can provide reliable operation over extended time periods.
