Patent EP-1030420-A1 (EP)
Inventor: ALAM MUHAMMAD ASHRAFAL
IPC: H01S5/40
Filed: 2000-01-19
Abstract: An array of VCSEL devices and a process for fabricating the VCSEL
array is disclosed. The VCSEL array emits light at n different wavelengths,
wherein n is at least two. A first portion of the VCSEL devices in the array
emits light at a first wavelength and a second portion of the VCSEL devices
emits light at a second wavelength. Each VCSEL device has an active region
consisting of alternating bands of quantum wells and boundary layers
bounded by top and bottom separate confinement layers. The active region is
bounded by top and bottom mirrors. The length of the active region of the
VCSEL devices that emit light at the first wavelength, λ s1 , is different from
the length of the active region of the VCSEL devices that emit light at a
second wavelength. 
     The array is fabricated by forming successive layers of material on a
III-V semiconductor substrate. The composition and dimensions of the
individual devices are first determined from the desired emission
wavelength, λ sn , of the devices in the array. Devices that emit at wavelength
λ s1  have an active region with length L 1 . Devices that emit at wavelength λ s2 
have an active region with length L 2 . From this information, the desired
difference in the length of the active regions of the devices in the array that
emit at different wavelengths, ΔL, is determined. In addition, the thickness
and composition for the individual quantum well layers is determined such
that the peak in the optical gain will be achieved at the desired wavelength
for each device. 
     Array fabrication is commenced by depositing at least one layer having
uniform composition and thickness on the III-V substrate. An oxide mask is
formed on the at least one layer of uniform thickness. The oxide mask is a
pattern of oxide pads that are used to control the MOCVD growth rate and 
the composition of III-V semiconductor material subsequently formed
thereon. The oxide mask pattern is selected to provide a layer of III-V
semiconductor material that meets the composition and dimension
specifications for the devices in the array. After the desired pattern is
determined, and the oxide pads are formed, a III-V semiconductor material is
formed on the substrate by MOCVD. During the growth step, the quantum
well layers of the desired thickness and composition are formed. The growth
is continued until the desired ΔL is obtained. MOCVD is then stopped and
the oxide mask is removed. A layer of III-V semiconductor material having
uniform composition and thickness is then deposited on the structure. This
deposition step continues until sufficient material is deposited on the
structure from which to form an array of devices having active regions with
the desired L n . A layer of material having uniform composition that will
become the top mirror of the VCSEL devices is then deposited on the
structure. The desired devices are then etched from the desired structure.
