Phase masks are the production tool used to write gratings in fibers and waveguides. Ibsen Phase masks incorporate unbeatable, interferometric (holographic) patterning technology into a production friendly Phase mask.

– for easy and cost-effective fabrication of Bragg gratings

Ibsen’s +1/-1 order principle Phase masks ensure quality and facilitate production in the telecommunications, sensor and laser industries. In the production of fiber and waveguide Bragg gratings, the Phase mask is illuminated by a high-power UV laser, typically an excimer laser or frequency-doubled gas laser. Self-interference between the diffracted orders produces the required pitch in the fiber or waveguide.

– for cost-effective fabrication of very low period gratings, typically in high refractive index materials

Low-cost production of gratings on planar wafers can be accomplished by use of the Nearfield Holography (NFH) technique, which employs a special type of Phase mask. The Phase mask is made for easy use in a specially modified mask aligner (commercially available from Suss MicroTec) with a conventional UV source as illumination. This technology has distinct production advantages over grating fabrication by direct holography or direct e-beam technology. In addition of fabrication of gratings on semiconductor DFB lasers, the technique is also advantageous in a number of other fine-pitch applications within the telecommunications and sensor industries.

Sample applications include:

• DFB lasers
• DBR lasers
• Integrated planar optics
• Sensors
• Biochips

– enabling single-step patterning of 2D gratings on planar wafers

Ibsen introduces 2D Phase masks for one-step generation of 2D square lattice grating patterns on planar wafers.

2D gratings can now be manufactured by the established Phase mask principles by simply exposing the wafer through an Ibsen 2D Phase mask at Bragg angle incidence, similar to the well known NFH Phase mask mode of operation (i.e. Bragg angle illumination).

By single exposure through an Ibsen Phase mask, and subsequent development of the photo-resist, and etching into the wafer, 2D square lattice grating structures as shown below can be written over large areas on a wafer.

The I-MON OEM series is compact, light weight and cost efficient, and is ideal for customers who want full control of all electronics and software, as the customer interfaces directly to the I-MON diode array. A Developer’s Kit is available to get started-plug-and-play.

The I-MON OEM Interrogation Monitors are designed for customers who want to make their own electrical interface directly to the diode array. This is ideal for customers who want full control of all electronics and software.

The I-MON 256 OEM and 512 OEM are from our new OEM series using a high speed InGaAs detector array for sensing at 1550 nm. The detectors are pin compatible, which means that electronics operating the 256 OEM can easily be designed to also operate the 512 OEM.

The I-MON 835 OEM offers a cost effective, yet high performing, sensing solution for 835 nm FBG’s.

High Speed Measurement Example
To demonstrate the capabilities of the I-MON 256 High Speed, Ibsen has made a measurement of the wavelength modulation from a piezo actuated FBG sensor with a 1 kHz tone. As seen from the picture to the right, the I-MON 256 High Speed resolves the modulation perfectly.
