"This investment will enable us to bring to our customers the Syntune advantages of low power consumption, small size, single chip simplicity and reliability, and rapid tuning that they desire," said Pierre-Jean Rigole, CEO.

Syntune produces tunable lasers to a unique design, known as "modulated grating Y-branch" or MG–Y. The key advantage of this laser design is that it is highly manufacturable, allowing the laser chip manufacture to be outsourced. This removes the need for dedicated fab facilities, and allows economies of scale to be passed to the customer. It additionally yields wide tuning range, high and even output power, high side-mode suppression ratio, low power consumption, and ultra-fast tuning.

"The Syntune product has decisive advantages in the high volume, small form factor market where tunability is a key differentiator. We are very impressed by the Syntune team and pleased to be part of their exciting growth," said Peder Holm, Investment Manager at InnovationsKaptial.

"Raising money now is not like raising money four years ago. This investment is a tribute to the compelling nature of the Syntune product, and the depth of the Syntune team," said Björn Broberg, Chairman.
