“…Monolithically integrated, low-cost and high-speed MW sources are extremely desirable for both dense and coarse WDM applications. All monolithically integrated MW VCSEL arrays are fabricated utilizing DBR/VCSEL layer thickness variations [34,[44][45][46][47], which are complicated processes and not readily scalable to large arrays.…”

A new concept of dielectric subwavelength grating has emerged. This grating leverages a high contrast in refractive indices for the grating medium and its surroundings. We will discuss how high-index-contrast grating (HCG) can manipulate light to achieve various extraordinary properties. We will discuss various designs to yield broadband, high-reflectivity mirrors for light incident in surface-normal direction and at a glancing angle, ultra high-Q resonators with surface-normal output, planar high focusing power reflectors and lenses, and ultralow loss hollow-core waveguides. The HCG will be a new, promising platform for integrated optics with applications for lasers, filters, waveguides, sensors and detectors.

“…Various types of multiwavelength VCSELs have been demonstrated. [1][2][3][4][5][6][7][8] We realized a multi-wavelength VCSEL array with a wavelength span of 190 nm 8) and a large number of channels of over 100. 9) A multi-wavelength VCSEL array enables us to realize high capacity throughput beyond 100 Gbps.…”

We present the ultra-compact hybrid integration of a 1060-nm-band multi-wavelength vertical cavity surface emitting laser (VCSEL) array with a tapered hollow waveguide multiplexer. The design of the hollow waveguide multiplexer is presented based on ray optics. We show the potential of a 12-channel array VCSEL output multiplexed in a multi-mode fiber. The device length is as small as 200 µm. The proposed hollow waveguide multiplexer would be useful for realizing compact wavelength division multiplexing (WDM) transceivers for optical interconnects.

“…There have been several reports on multiwavelength VCSELs based on different approaches. [2][3][4][5][6][7][8][9][10] However, there still remain difficulties in the precise on-chip wavelength control of multiwavelength VCSELs because fabrication errors in distributed Bragg reflector (DBR) thicknesses and oxide apertures limit wavelength accuracy. If we can define the lasing wavelength precisely through a postprocess of VCSEL fabrications, the fabrication of large-scale multiwavelength VCSEL arrays can be made much easier.…”

We proposed a trimming technology for the precise control of the lasing wavelength and lasing performance of high-contrast subwavelength grating (HCG) loaded vertical-cavity surface-emitting lasers (VCSELs). The trimming is based on the postprocess surface etching of HCG. Our result obtained using rigorous coupled wave analysis (RCWA) shows a possible precise wavelength tuning range of 3 nm for GaAs-based HCG-VCSELs. Our preliminary experiment reveals an expected smallest wavelength trimming of 0.07 nm.
