The beauty of VCSEL is that compare to traditional lasers, it makes packaging become extremely simple, more robust and durable, very compact, and lower manufacturing costs.

Through the two-dimensional stacking, many laser emitters can be integrated on a single chip or package substrate, thereby achieving higher power output, and reducing dependence on additional optical designs.

These incredible abilities have been widely confirmed and applied in LiDAR and certain laser medical fields. It has changed the product design of this application field, simplified redundant components, eliminated a lot of complexity of these systems, and made it more miniaturized, low cost as well as high performance, revolutionizes the limitations of traditional lasers.

Combining many of the desired features of an LED and the advantages of a laser diode, VCSEL offer many advantages in sensing applications over infrared LEDs. These devices require substantially lower drive currents to obtain the same amount of output power as LEDs. This feature allows VCSELs to be used in low power consumption applications such as battery-operated equipment.

Compared with the traditional EEL (Edge Emitting Laser), VCSEL has better wavelength stability, the wavelength temperature coefficient is 0.07nm/deg or less while that of EEL is 0.25-0.3nm/deg. VCSEL has two characteristics of smaller divergence and circular spot, which is beneficial for collimation or focusing and simplifies the coupling link, it also helps to reduce costs and improve reliability. EEL suffer from catastrophic optical damage (COD) at the facets, a common problem causes reducing reliability in laser diodes. VCSELs do not show this damage as the end facets are designed differently. Moreover, VCSEL has the advantages of high reliability, wide operating temperature range, and can better meet industrial requirements of lasers.

As VCSELs are a surface-emitting laser chip like LEDs, SMD (Surface Mount Devices) is its natural packaging form, and the packaging has many dominant advantages, such as good heat dissipation, easy mounting with electronic components, small size, etc.; yet in SMD packaging may cause deviation in alignment with optical components, most likely when matching with optical lens systems, so in laser industry there has a pressing demand for TO packaging of VCSELs. To satisfy the requirements, Brightlaser delivers TO package VCSEL since 2018. So far, it has formed abundant TO packaged VCSEL product line with various wavelengths, different optical power, and product application scenarios. And it has been widely verified by the market and has been highly recognized by customers around the world.

 

In optical communication, Brightlaser provides TO46 and TOSA VCSEL devices of 5Gbps and 10Gbps that are compliant to MIL-883 and GR468 standards.

Besides TO46, TO56 is another popular package form in 670nm, 808nm, 850nm and 940nm, mass production in continuous and pulsed VCSELs, which has been used in laser modules, range finder sensors, 3D scanners and other applications; In pulse mode and  low duty cycle and nano second pulse, peak power can go from 10W to 100W+, widely used in dTOF laser ranging finder sensor, 3D dTOF cameras and lidars. 

Re-embedding dome lens in TO package can generate narrow divergence beam, suitable for long-distance applications, without additional optics, thus can reduce system cost. Brightlaser’s VP series combine all the performance advantages of a VCSEL with the addition of a power monitor diode for precise control of optical power.

In addition to TO packages, cost-effectively plastic-encapsulated dip VCSELs, can replace plastic-encapsulated LEDs as VCSELs are of high power density, higher SNR to ambient light interference, for low cost sensors such as proximity sensors and ranging finder sensors.
