Spire to sell VCSELs in Japan

Spire Corp. (Bedford, MA) and Shimadzu Corp. (Kyoto, Japan) have formed a strategic alliance to sell vertical-cavity surface-emitting-laser (VCSEL) products in Japan. The semiconductor diode lasers are used in data communications and high-speed optical interconnect systems for telecommunications switching gear, as well as optical data storage and laser printers. Spire is starting production of single VCSELs and VCSEL arrays. The first products are designed for such communication applications as Gigabit Ethernet and Fibre Channel. Shimadzu will distribute Spire products in Japan and will also start production of VCSEL devices at its fabrication facility in Atsugi. The companies expect the market for VCSELs to be more than $100 million by 2002.

FIGURE 1. In the scalable setting of a spatial photonic Ising machine, binary spins are encoded in the phase of a laser beam (green) by spatial modulation. Tailoring of the beam’s amplitude fixes spin-spin interaction. To find the ground-state spin configuration, the machine recurrently evolves according to a feedback signal from the camera plane. By design, maximizing the intensity in a target region (blue square) corresponds to a spin state with minimum energy.
