IX. VCSEL-B

INTEGRATION Technology

...A wide variety of functions, such as frequency tuning, am-

plification, and filtering, can be integrated along with SELs by

stacking. Another possible way of moduling is to use the micro-

optical bench concept [76] to ease the assembling of compo-

nents without precise alignment, as shown in Fig. 14. More-

over, a 2-D parallel optical-logic system can deal with a large

amount of image information with high speed. To this demand,

an SEL will be a key device. Optical neural chips have been

investigated for the purpose of making optical neurocomputers

.....Vertical optical interconnects of LSI chips and circuit boards

and multiple fiber systems may be the most interesting field re-

lated to VCSELs. From this point of view, the device should

be as small as possible. The future process technology for it, in-

cluding epitaxy and etching, will drastically change the situation

of VCSELs. Some optical technologies are already introduced

in various subsystems and, in addition, the arrayed microoptic

technology would be very helpful for advanced systems.

The most promising application will be gigabit LANs. GaAs

VCSELs emitting 850 nm of standardized wavelength are

mass produced for

1–Gb/s LAN and simple optical links.

For high-end systems, 1300–1550-nm devices are requested.

By using VCSEL and micromachining technology, we demon-

strated a temperature-insensitive surface normal Fabry–Perot

filter for add–drop filtering in WDM. To establish an appro-

priate module technology utilizing VCSELs, an MOB has been

investigated together with planar microlens array. Related to

planar microlens array application and ultra-parallel informa-

tion processing, an image recognition system is investigated

using synthetic discriminant function (SDF) filtering.

In summary, the ultra-parallel optoelectronics based upon ar-

rayed devices, including VCSELs, will open up a new era for

the 2000 millennium
