Reflective silicon binary diffraction grating for visible wavelengths

HPL-2011-15 Reflective silicon binary diffraction grating for visible wavelengths - Peng, Zhen; Fattal, David A.; Faraon, Andrei; Fiorentino, Marco; Li, Jingjing; Beausoleil, Raymond G.
Keyword(s): Photonic interconnect
Abstract: We introduce a new device based on sub-wavelength resonant grating technology. Using a single lithography step we built a reflective binary grating that mimics the functionality of a blazed diffraction grating in a flat geometry. We have also demonstrated that efficient sub-wavelength resonant devic ...

dpt

DPT(4)							   BSD Kernel Interfaces Manual 						    DPT(4)

NAME

     dpt -- DPT RAID Controller SCSI driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device dpt

	   For one or more EISA cards:
	   device eisa

	   For one or more ISA cards:
	   device isa

	   For one or more PCI cards:
	   device pci

	   To allow PCI adapters to use memory mapped I/O if enabled:
	   options DPT_ALLOW_MEMIO

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   dpt_load="YES"

DESCRIPTION

     The dpt driver supports DPT RAID SCSI controllers.

     SmartRAID (PM3???) are "Enterprise" class cards, and SmartCache (PM2???) cards are in the "Workstation" class.  The Gen 4 Smart Cache IV
     products were a re-issue of the Gen 3 utilizing upgraded (and cheaper to produce) silicon.  The PM3334 (Smart RAID III) was not revamped as
     there was no upgraded silicon (68040 processor) and it was using the best DPT made.  Note there has been customer confusion over the faster
     enterprise class card supported by this driver being an older generation.	The Gen5 cards are supported by the asr(4) driver.

HARDWARE

     The dpt driver provides support for the following RAID adapters:

     o	 DPT Smart Cache Plus
     o	 Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
     o	 Smart RAID II (PM3?2?, PM3021, PM3222)
     o	 Smart Cache III (PM2?3?)
     o	 Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
     o	 Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
     o	 Smart RAID IV

HISTORY

     The dpt driver first appeared in FreeBSD 2.2.6.

AUTHORS

     The dpt driver was written by Simon Shapiro and ported to the CAM SCSI system by Justin T. Gibbs.
