Microfabrication
StockerYale operates an extensive class 100 clean room and microfabrication
facility. This facility is equipped with a variety of devices that
serve in the manufacturing of the company's illumination and diffractive
optics products. The company's clean room is particularly well-equipped
for the hermetic packaging of laser and light-emitting diodes,
and for the metallized fiber pigtailing and alignment of these
light sources.

| StockerYale's Atomic Force Microscope (AFM) is used to characterize the profiles of our diffractive gratings. Shown in the above illustration is an AFM image of the surface of a phase mask with a period of 350 nanometers. |
StockerYale's diffractive optics are also fabricated in the class 100 clean
room facility. These optical elements are made using two complementary
technologies: holographic recording of gratings, and computer generated
holograms (recorded using photomasks). The two methods serve to produce
a wide assortment of diffractive optics and grating products, including
beam splitters, pattern generators, high-quality binary masters etched in
fused silica, and silica phase masks. Other applications in which StockerYale's
diffractive optics are used include satellite communication, bio-chips,
and optical encoders for micro-positioning.

| Primarily used for the hermetic packaging of laser diodes, StockerYale's glove box is one of the many high-tech devices found in our class 100 clean room. |
Operating a state-of-the-art microfabrication facility, StockerYale is
ideally equipped for supporting strategic partnerships in photonics research.
We welcome the opportunity to assist our clients in the development of
new, technically challenging technologies and products.
 |
| Using in-house software, our diffraction grating design
team creates binary photomask patterns, which are recorded onto a silica
substrate. (Figure 1) By mounting the resulting diffractive element
on a Lasiris™ laser, we generate a precise 12 x 12 matrix of
laser beams, which is typically used in machine vision applications.
(Figure 2) One of StockerYale's unique strengths is the combination,
within the same firm, of the Lasiris™ diode laser product line
and the in-house gratings and lens capabilities. These competencies
together allow the company to produce structured laser light generators
that meet demanding custom requirements. |
