A photonic integrated circuit (PIC) chip comprising an array of modulated sources, each providing a modulated signal output at a channel wavelength different from the channel wavelength of other modulated sources and a wavelength selective combiner having an input optically coupled to received all the signal outputs from the modulated sources and provide a combined output signal on an output waveguide from the chip. The modulated sources, combiner and output waveguide are all integrated on the same chip.

Photonic integrated circuit (PIC) chips

A photonic integrated circuit (PIC) chip with a plurality of electro-optic components formed on a major surface of the chip and a submount that includes a substrate that extends over the major surface of the chip forming an air gap between the substrate and the major surface, the substrate to support electrical leads for electrical connection to some of the electro-optic components on the chip major surface.

A method for leak testing of a hermetic package closure comprises the steps of: creating a pocket in a lid; plating the lid; placing solder in the pocket; melting the solder in the pocket; drilling a hole through the solder and the plated lid creating an unplated area on the plated lid; testing the hermetic package closure for leaks through the hole; heating the solder reflow, wherein surface tension of the solder over the hole and the unplated area enable the solder to form a hermetic closure.
