We report on the detection of human anti-dengue antibodies from serum samples using a compact optoelectronic label-free biosensor. The system consists of a tunable vertical-cavity surface-emitting laser, guided-mode resonant sensor surface, and two silicon pin detectors. This novel biosensor demonstrated sufficient sensitivity in a clinical-relevant assay, making it a potential new platform for si...Show More
Harsh environment temperature and strain sensor using tunable VCSEL and multiple fiber bragg gratings
2007 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference
Year: 2007 | Conference Paper |
Cited by: Papers (8)
Harsh environment applications, such as aerospace and oil extraction, require small, lightweight and robust sensors. The new temperature and strain sensor system presented here consists of a tunable VCSEL, optical circulator, fiber with Bragg gratings at different wavelengths, and pin detectors. It has broad dynamic range, high sensitivity, low weight and a very simple detection scheme. When compa...Show More

Compact label-free biosensor using VCSEL-based measurement system
C.F.R. Mateus;M.C.Y. Huang;P. Li;B.T. Cunningham;C.J. Chang-Hasnain
We report an ultracompact label-free biosensor that uses a vertical-cavity surface-emitting laser (VCSEL)-based measurement system for the characterization of biomolecular interactions. It consists of a VCSEL, a plastic guided-mode resonant filter, and two p-i-n detectors. The system has demonstrated very high sensitivity to molecules on top of the sensor.Show More
Broad-band mirror (1.12-1.62 μm) using a subwavelength grating
C.F.R. Mateus;M.C.Y. Huang;Lu Chen;C.J. Chang-Hasnain;Y. Suzuki
We report the first experimental demonstration of a novel single-layer subwavelength grating (SWG) that has >500-nm-wide reflection spectrum from 1.12-1.62 μm and very high reflectivity (>98.5%). This SWG is scalable for different wavelengths by simply changing the grating dimensions, which, thus, facilitates monolithic integration of devices over a wide range of wavelengths.Show More

We report a new label-free biosensor system for protein interaction characterization. The system consists of a VCSEL, a plastic guided mode resonant filter, and a pin detector. The sensor has high sensitivity and ultra compactness, consumes low power, and can be fabricated in 2D arrays.Show More
Tunable micromechanical optical filter using a torsional structure
C.F.R. Mateus;Chih-Hao Chang;C.J. Chang-Hasnain;S. Yang;D. Sun;R. Pathak
Optical Fiber Communication Conference and Exhibit
Year: 2002 | Conference Paper |
Cited by: Papers (4)
We demonstrated a torsional micromechanical tunable optical filter with potentially far large tuning range and free of damages resulting from capacitor discharge. The tuning range is above 100 nm and was limited by the tunable source available for testing. The insertion of the filter in an optical data link causes no power penalty. The torsional MEMS design can be readily transferred to a tunable ...Show More
General design rules for MEMS tunable optical filters
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges
Year: 2002 | Conference Paper |
Summary from only given. Tunable optical filters are important for applications such as DWDM optical networks. Micromechanically actuated filters are desirable because of their wide tuning range, design flexibility and high yield. The device structure consists of epitaxial layers forming a single Fabry-Perot cavity, having two distributed Bragg reflectors (DBRs) and an air gap in-between. We recen...Show More
Widely tunable torsional optical filter
C.F.R. Mateus;Chih-Hao Chang;L. Chrostowski;S. Yang;Decai Sun;R. Pathak;C.J. Chang-Hasnain
A broad range tunable optical filter using a torsional micromechanical structure is presented. The device has a continuous tuning range over 100 nm, from 1500 to 1600 nm, and the structure eliminates the potential catastrophic discharge problem associated with electrostatic micromachines. Transmission of a 2.5-Gb/s directly modulated 1550-nm vertical-cavity surface-emitting laser through the tunab...Show More
The polarization isolation of birefringent fiber half-couplers is locally observed and characterized when the device is submitted to the various steps of its fabrication. After stripping and aligning the fiber, the polarization is not affected. The mode coupling rises to the order of -40 dB after cementing and -20 dB after polishing. When the substrate is released from the jig, the set relaxes and...Show More
Measurements of polarization cross-coupling in a tension-coiled polarization-preserving fiber by optical coherence domain polarimetry
1999 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference
Year: 1999 | Conference Paper |
Cited by: Papers (1)
Measurements of polarization cross-coupling in a polarization-maintaining fiber (3M FS-PM-6621) under two coiling situations are carried out by optical coherence domain polarimetry. In the first situation, it is coiled around a 25.4 mm diameter piezoelectric tube and the applied voltage is increased from 0 to 900 V. In the second, the fiber is tension-coiled around a 24.6 mm diameter passive drum ...Show More
Modeling of birefringent fiber-optic directional couplers
1999 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference
Year: 1999 | Conference Paper |
Cited by: Papers (1)
Extending a coupled mode theory of directional couplers with parallel step index fibers, an analytical solution for the coupling coefficients of curved and birefringent fibers is obtained. This model allows a fast simulation to describe the behavior of the coupler as part of a complexer optical circuit. Numerical results for the power exchange between fibers 3M-FS-HB-4611 are presented and discuss...Show More
